I'm not sure what bore size or thickness to go with. I have 081 casting and was told stock I have 9:3:1.

I will be running a

95 Lt1 cam
95 Lt1 intake
Hooker super comp shorties.

Higher compretion on 87 octane. Please help.

I know TPIS has 350 gaskets that ups the CR by half a point but I don't know if they have one for a 305?

There isnt one. You already have a thin gasket stock, the only thing thinner would be to run no gasket at all.
Have to go another route to up your compression ratio.

aw k.

Felpro 1094 the compressed thickness is .015. The only thing with these are, they are a rubber coated shim and everything has to be flat in order for them to seal correctly.

Now with that said, I just slaped them on there and called it good. lol

is that a stock replacement? Or will that up to cr. I wonder what it will be with that gasket

Practically nothing.

What Max said. about .5 of a point.
