what will the compresion be on a ly6 .030

I think I found the Cam,

Lunati 60531 should work good for long travel sand car.

It is a 227/238 lift is in-583 ex-600 on a 112, this was made for the l92 head.

if I have 9.7 compression with a .051 head gasket what will I have if I use a .030 head gasket?

Thanks.

depends on alot of things. deck height of pistons, dome +/-, piston releif volume, head cc, etc.........
If pistons are .010 out of the hole as they normally are, you wont want to run the .030 gaskets. you'd be better off milling the heads.

Did not check the ratio, but I shaved .020 off seems to be fine, ls1 intake, Cam, and throttle body, fast injectors, and electromotive computer made 560 hp on the dyno.
