sellecting cylinder heads

you might want to watch this, its comparing the vortec SBC heads vs a CNC aluminum 210cc SBC head on a 383 (yes a head that large actually works and has a great deal more low and mid rpm torque that you may have been lead to believe, with 210cc ports and yes there are better heads in the...

Buy used, cleaned Vortec heads with old valves and springs + Vortec intake manifold = $570?

*Currently I have this*

Yes, I would make sure to get the correct valves. I was asking for opinions on the type of heads to get based on the camshaft and engine I have.
Information overload but looks like lots of good links. Thanks!

Grumpy · Nov 19, 2020

you've got dozens of options, but I generally use the brodix IK 180 cc heads on similar builds,
or the brodix 200 cc port heads on more aggressive builds,used mostly on street driven cars
simply because they are high quality at a reasonable price,
and you see few issues, something thats much less true in some less expensive heads,
and it really sucks to spend $600-$700 on the cheaper heads and find out you have
valve train clearance, component alignment, the wrong valve spring load rates,
port flow restrictions, valve sealing, rocker arm algnment, push rod to guide clearance .
,valve seals that don,t fit correctly, spring bind and similar issues

for an off brand head these promax 215cc SBC heads,
provide a decent value once cleaned up and a decent valve jobs been done
(ideally a multi angle valve job and use steel cup valve spring seats , to protect the aluminum heads,
and light weight retainers and maybe beehive valve springs)(smaller diam. retainers weigh less and beehive valve springs less prone to harmonic valve spring surge issues) and (a rocker stud girdle might help also)
as usual talk too both the cam and head manufacturers and your machine shop, or cylinder head shop guy you trust

obviously you'll need the correct valve springs and a decent hydraulic roller cam,
with between about 230-240 duration and about a .550-610 lift (use 1.6:1 ratio roller rockers)
that in turn will require a manual transmission or a 3200 rpm stall converter and about a 3.54:1-4.11:1 rear gear,
and about a 383-406 cid and about 10:1-11:1 compression ratio, in most cars to max power
