305 head gaskets
 

What head gaskets would you sugest for a 0.030" over 305, I dont want to run the stock 0.041" thick gaskets I want to be around 0.026- 0.020" thick compressed. The only ones I can find are from GM performance, just wondering if anyone else has a line or a lead on some different brands I could look into.

Thank you before hand. Cam

Try Cometic... a bit more money but available in any specified thickness..., they are also reusable, a bonus considering the price!!!!
good luck fellow Canuck!!!

Re: 305 head gaskets
 

Anyone else have a source other than GM perf as cometic does not carry anything under a 4.100" bore gasket. The 305's require somewhere in the 3.800" range bore on the gasket, if I go too big I am going to loose comp. and sealing capabilities and maybe the chance of heat soaking the spark plug cooling jackets.:confused:

We have ordered the 305 Cometic gaskets several times with the small bore.

Just ordered a pair 2 weeks ago for the camaro. It took about 5 day to get. You give them the bore and thickness and they custom make them. They were about 90 dollars a gasket but they reuseable. Call them they will take care of you.
