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.
