Ok, if i have a 30 over 455 with a 4.250 stroke, 6.8 rod, o decked with a 56cc cylinder head and a .039 gasket.....Whats my compression? Ross flat tops 2 valve relief.............

Now same motor combo, but lets try to get it to 10 to 1......How much dish and head gasket would i need to get it down there? And would it be reliable for a blower application?
