i have a 350 60 over my piston have .100 dome my heads are 882 76cc my cam is edelbrock rpm non roller air rpm intake with 750 holley vs i need heads for this engine without to high compresson what types or brands can i use.and do i have to stay only with 76cc heads.

 

Your actual compression ratio will depend on a few things like piston deck clearance .

wether you can get away with 64cc heads depends on the actual cr, the fuel octane and to some degree the cam timing.
Most popular performance 64cc heads are also available as 67 or 70 or 72cc chambered heads.
A aluminum head will tolerate a little more compression for the same octane as a iron head.
A 64cc head can be tweeked a bit with a die grinder to open up the chamber a bit if nessessary. helps breathing too.
generally 10:1 for iron 10.5:1 for aluminum.

Anything would be an improvement over the 882's you have now... What new heads do you have in mind?

 

im thinking on the line of some world torquer 76cc or world sportman2 72cc heads both with 202 valves but im still open for a better set that will work with my rpm cam and intake .

 

I'd pass on the World S/R's out of the box flow is modest at best even for a replacement head.
there are much better ones now.

Dart, Protopline, Brodix are good so are AFR.. Lots to choose from.
from entry level SS-S/r type, vortec , or iron eagle/ iron lightning.

The SportsmanII is the head that started it all, but there are better ones now.
if you don't mind doing some basic porting after ya get 'em, the Sportsman II's can rock.

A set of Matching Edelbrock RPM'S are a good buy too.
They work and respond to hand tweeking as well.
same with ETEC 170's

you'd be best to remove your heads and measure the piston deck clearance first before you commit to one chamber size or another. Aluminum typically will tolerate more cr.

I'm on my second set of Vortecs. Lot of bang for the bucks. Recommend them. Gained a full second off the ET from 882's.
The chambers on these heads seem to be more detonation tolerant too. (fastburn)
there are others on this board that are running vortecs with the same dome piston with good results. May need a little spike of Tolene ( paint store) in the gas tank now and then.
Lots of options ....
