your bound to notice I install links too useful info in most threads,
now obviously not all the info, posted in all threads will be helpful in all cases,
but you'll eventually come to realize the value of reading thru the info links.
theres a great deal of useful info, in those links
info that you might think is useless to you now, but you'll be amazed at the number of times in the future your going to say to yourself...., damn! I remember reading something about that, now where was that posted, and a brief search will turn up your info!, info you swore at the time was a waste of your time to read thru, I know that's been very common for me and I'm sure it will be for those guys that really want to learn how and why things work!.

dip the head bolt threads in sealant before installation to prevent coolant leaks
http://www.mifbody.com/vbulletin/showth ... LS1-motors
if you don,t have a particular engines torque sequence its a safe bet that you start with the center head bolts and tighten each , in stages in a spiral outward pattern, then repeat the sequence with each increased torque setting movng in that same spiral increasing diam spiral moving from the center to outer bolt locations.
SBC HEADS
Ive used it for decades and it works, simply clean both the head and block with a clean acetone soaked lint free rag, spray both sides of the head gasket until damp, install with the head and torque to proper tension

one very good CD to get if your a beginner to engine assembly
http://www.themotorbookstore.com/resmchstvi.html
theres a good deal of info in the sub links of this thread above and below
check with the bearing manufacturer and look in your shop manual, first BUT THESE specs WILL BE CLOSE OR EXACT in most SBC applications
Piston-to-wall clearance: 0.005 inch
Main bearing clearance: 0.023-0.027 inch
Rod bearing clearance: 0.025-0.027 inch
Rod side clearance: 0.016-0.020 inch
Rod side-to-piston clearance: 0.125 inch
Ring end gap: 0.022/0.020/0.032 inch
Piston-to-head clearance: 0.041 inch
ring end gap, .004 PER inch of bore diam, IE 4" bore .016 end gap
HYPER EUTECTIC pistons

circletrack said:Stock Bearing Clearances
Adjusting the clearance is easy, but probably a bit more expensive than most of us would prefer. Most quality bearing manufacturers make three versions for all the popular styles. First, there’s the standard bearing. This is where you start. If you find you need more clearance, you can purchase an undersized bearing. This means the bearing shell is thinner, which creates 0.001 more clearance than a standard bearing. An oversized bearing is the opposite. It’s thicker and takes away 0.001 of clearance.
One one-thousandth of an inch is a big jump, but you can actually make adjustments in 0.0005 increments—that’s one-half of one thousandths of an inch. To do this you mix half the shell of a one-over or one-under bearing with half the shell from the standard bearing. This means you may have to purchase a couple sets of bearings to get everything just right in your race engine, but sometimes that’s the price you have to pay. Just remember when mixing shells to always keep the sizes in the same alignment. In other words, if you’re using one-unders with standards for your main bearings, put all the one-unders in the cap with the standards in the block side of the housing bore, or vice versa. So with that said, let’s get on with it.
The general rule of thumb for bearing clearances is 0.0010 inch for every 1 inch of journal diameter. That's true for mains and rods, and applies to almost all engines. For the small-block's 2-inch rod journals, that means 0.002 inch of clearance between the rod journal and bearing, by the rule of thumb. The GM-specified tolerances are 0.002 to 0.0025 inch, which lines up well with the rule. Side clearances come in at 0.010 to 0.020 inch, as specified by GM. The clearance rule applies to most engines, but it's generally best to avoid going below 0.0020 inch on any bearing, regardless of the journal diameter.

These specs are for stock-type bolts with light engine oil applied to the threads and the underside of the bolt head. Moly and other lubes offer reduced friction and increased bolt tension, which will affect the torque figure. If you use aftermarket performance bolts like ARP's, you should follow the recommended torque specifications.
