Question about .015 head gaskets - FelPro 1094
Hello, I'm a new member. I have a 1980 Corvette with a 3.73 rear and the motor on a stand.
I want to increase the compression on my small block from approximately 9:1 to 9:5 or more to accommodate a Summit 224/234 .465/.488 cam that I've purchased. I'd like to use FelPro 1094 which is a .015 as opposed to the .041 that I already have. Are there any considerations or compromises to take into account when using a thinner compressed head gasket? It's seems obvious that .015 is much lower than the standard size head gaskets out there so that's why I'm questioning.
My engine is a .030 over 350 with 041 .194/64cc heads. The pistons are flat cast aluminum with 4 valve reliefs. I tried to cc the cylinder volume at 1/2" and made a mess, but I came up with about 9.1 to 9.3 compression. I measured the piston in the hole and they're down there pretty far - about .050. I really want to try to put this top end together myself and learn how to do this in the process. This is a somewhat low-buck project so I'm not installing new pistons for higher compression. Thanks very much for any input.
