I know that pontiac's compress to .041 with a stock gasket, I've been looking around and was thinking about going with a cometic head gasket that seems to be specifically for a 350 bore with a compressed thickness of .027. Is that a good necessary? They seem expensive. Running NA 300 or so HP.

some guys run Fel pro and some like Victor reinz. Both will have arguments as to why theres is better.
A .027 cometic? not necessary, or even desireable.
They require an insanely clean finish on the heads and block surface, so both need machined. If your going to machine the block deck, just zero deck it , run the .041 gasket, get some quench and be happy.:cool:
Dont waste your time and money with a cometic. Your build doesnt warrant that.
Look at my project journal, the 389 I have uses Fel pro head gaskets. It will destroy the rear tire (one wheel wonder) from a dead stop.
9.5 to 1
.046 quench
crane 272-2 cam 218-226 @.050 112lsa
crosswinds intake+ Q jet
2.5 inch duals
I am guessing my HP is around 365-375.
