been looking at heads for my 85 camaro z 28. 305 is bad and im putting in a 350 with pretty much stock internals , hypereutectic flat top pistons, will be keeping the stock tpi setup but going with an adjustable pressure regulator. the heads i am looking at are a stock gm head 64cc with 202 160 valves and the cam i plan on running is a crane energizer #100042 which specs out at:
.440intake
.440exhaust
adv dur 266 int, 266 exh
.050 dur 210 int 210 exh
is this cam going to work ?
is the 202 160 valve size going to be too big?
is this going to make decent power?
lemme know before i waste my time

Lotta reference on this swap in arcives, 64 CC with flat tops might put you above pump gas,,,check your C.R.

my cr is going to be at about 9.5 to 1 with a 64 cc head and flattops w/4 valve relief pistons. may change a little based on my head gasket, should be just fine on pump gas, but will my stock calibrated computer for my tuned port with the 19 lb injectors and an adjustable fpr, work with these large valve heads and bigger cam, it is a mass air system

Depending on the cam, might be drivable while you whittle out a custom chip for your setup..
