What !!!!! Unless you can machine off a good chunk from your heads, that'sthe only way to gain more compression on a Flathead. The pistons ARE what gives you the compression. And most off the shelf heads, including Edelbrocks, will only get you about 9.5 to 1, with a slightly domed pistons. Flat tops might give ya, uhhhhhhh, 6 to 1.
