SMALL CHAMBER PRODUCTION "ON CAR" CYLINDER HEADS -By Racerguy..I just borrowed the page from him..

"462" – Could be 3890462, 3891462, 3990462. The 462 is one of the best flowing production SBC heads. They were used between 1962-1968 on various HP versions of 302, 327, or 350 engines. They could have come with either 1.94/1.50" or 2.02/1.60" valves, had 64CC combustion chambers, DO NOT have accessory holes, intake port volume should be 161CC's, exhaust port volume should be 65CC's. These heads have double hump casting marks.

"461" – Could be 3782461, or 3782461X. These were an excellent performance head. The regular 461 casting was used between 1964-1966 and could be found on 327 engines. They had 2.02/1.60" valves, a 64CC combustion chamber, DO NOT have accessory holes, intake port volume of 161CC's, exhaust 62CC's. These heads have double hump casting marks. The "X" castings had the same port configuration, but had larger port volumes, they DO NOT have accessory holes. The intake port on the "X" casting was 172CC's, and the exhaust port was 62CC's, valve sizing was 1.94/1.50". The "X" heads had double hump casting marks as well.

"291" – Could be 3912291, or 3917291. This is another good performance casting. They were found on 1967-1968 302, 327, or 350 engines. They could have either 1.94/1.50" or 2.02/1.60" valves, 64CC combustion chambers, DO NOT have accessory holes, intake port volume should be 161CC's, exhaust port volume should be 65CC's. These heads have double hump casting marks.

"492" – 3991492. Another good performance head. They were found on 1970 LT-1 engines. They had 2.02/1.60" valves, 64CC combustion chambers, DO have accessory holes, intake port volume should be 161CC's, exhaust port volume should be 62CC's. These heads have double hump casting marks. This particular casting head was also available as an "over the counter" head from GM in straight or angle plug configurations.

"186" – 3927186. Another good performance head. They were found on 1969-1970 302 and 350 engines. They had 2.02/1.60" valves, 64CC combustion chambers, DO have accessory holes, intake port volume should be 161CC's, exhaust port volume should be 65CC's. These heads have double hump casting marks.

"292" – 3917292, or 340292. Both are good performance heads. The 3917292 was found on 1968 327 and 350 engines, had 1.94/1.50" valves, 64CC combustion chambers, straight plug configuration, not sure on the accessory holes, and I do not have any port volume data on these heads. These heads have double hump casting marks. The 340292 was available from GM "over the counter". This version had angle plug configuration, 2.02/1.60" valves, 64CC combustion chambers. These were known as the "Turbo" heads.

"041" – 3947041, also 3947041X. A good performance head. They were found on 1969-1970 302 and 350 engines. They had either 1.94/1.50" or 2.02/1.60" valves, 64CC combustion chambers, DO have accessory holes, I don't have port volume data for the regular 041, the 041X intake port should be 165CC's, the 041X exhaust port should be 65CC's. These heads have a single somewhat triangular shaped casting mark (slope on the upper left).

"040" – 3947040. A good performance head (I have read). Supposedly these heads came on 1968 327 truck engines. They had 1.94/1.50" valves, 64CC combustion chambers, DO NOT have accessory holes. I do not have any port volume data for these castings. These heads also had a single triangular shaped casting mark (slope on the upper left).

"187" – 3927187. Another good performance head (I think). They were found on 1969-1970 350 engines. I believe they had 1.94/1.50" valves, 64CC combustion chambers, DO have accessory holes. I do not have any data on port volumes for this casting. These heads have double hump casting marks.

"414" – 3973414. A good performance head. They were found on 1970 350 LT-1 engines. They had 2.02/1.60" valves, 64CC combustion chambers, DO have accessory holes. I do not have any port volume data for this casting. These heads have double hump casting marks.


LARGE CHAMBER PRODUCTION "ON CAR" HEADS

"487" – 3973487, OR 3973487X. The regular casting was found on the 1971-1972 350 LT-1 engines, had 1.94/1.50" valves, 76CC combustion chambers, DO have accessory holes, intake port volume should be 161CC's, exhaust port volume should be 65CC's. The 487X had 2.02/1.60" valves.

"441" – 3932441. This head was found on the 1969-1970 350 engines (255hp 350), it was a decent flowing large chamber head. It had 1.94/1.50" valves, 76CC combustion chambers, DO have accessory holes, intake port volume should be 161CC's, exhaust port volume should be 61CC's. Not to be confused with 3923441, which was a 1.72/1.50" valve, 327 truck head.

"624" – 462624, 426624, or 458624. The 458624 was a truck head, with 1.72/1.50 valves – non performance. The other castings were used mid 70's and up on 350 engines, they came with 1.94/1.50" or 2.02/1.60" valves, had 76CC combustion chambers, DO have accessory holes, intake port volume is 161CC's, exhaust port volume is 62CC's. These heads are made of thinner castings and are prone to cracking.

"882" – 333882. These heads were found on early-late 70's 350 and 400 engines. They had 76CC combustion chambers, 1.94/13.50" valves, DO have accessory holes, intake port volume is 160CC's, exhaust port volume is 60CC's. These heads are made of thinner castings and are prone to cracking as well. The exhaust port on these heads is rather weak in my humble opinion, and is not considered to be a good performance head. I have read some flow numbers on the internet regarding the 882's, and I have a hard time believing some of the flow numbers people are posting on these particular castings. I did extensive flow testing on several of these particular castings, and was not very impressed with their flow characteristics. The 441 or 487 are a much better large chamber head (in my humble opinion). The 882 intake port is very close to that of the 624, the exhaust side is where the 882 is weaker.


OVER THE COUNTER GM IRON HEADS

"492" – See listing above.

"3973370" – A good over the counter head. They had 64CC combustion chambers, supposedly straight or angle plug configuration. Used a set of these on all 3 of my 383 strokers, they originally came with 1.94/1.50" valves. We did some major port massaging and installed 2.02/1.60" valves, they responded very well to the modifications and worked very well. The combustion chambers were 64CC's. These were a decent iron head, with a lot of potential for performance.

"3965742" – Another over the counter GM iron head. I have no data on these particular castings, other than they were angle plug configuration.

Small Block Chevy Gen I Cylinder Heads by Casting Number

10033867 – V8 aluminum, Pontiac 23 degree head, 62cc chambers, angle plugs, 196cc intake ports
before you spend a good deal of money porting and un-shrouding any iron cylinder heads, keep in mind aluminum heads are easily repaired in a skilled and experienced automotive machine shop thats equipped to do those repairs but damaged iron cylinder heads are either much harder to repair or good door stops
http://garage.grumpysperformance.com/index.php?threads/iron-vs-aluminum-heads.389/#post-7266

The famous double hump cylinder heads, the #3782461 and #3782461X used 1.94/1.50-inch valves. These were commonly called “Fuelie” heads because they were released with mechanical Rochester fuel injection on the stock engines.

What timing. I see the listing in black for the intake I'm currently interested in #488945 Pontiac 1972. Seller says its for a ram air IV for $750, that's a lot of money, I need to know if it is worth getting.
The list above calls it a two piece aluminum?
