stud mount is a good setup, pedistals i believe u have to shim up to get the correct geometry, the compression ratio will vary, depends on the piston you are using, but the head chamber size will raise or lower your compression ratio, say u are running a stock piston and head, which i believe is 9.0:1 compression with flattops, if you run a dome piston with the same head your ratio could be 10.2:1, depends on the spec the piston manufacturer gives with certain chamber heads, look it up in summit or jegs, you'll see the different ratios with the chamber sizes....
