heads... exhaust... intake

Mopers right. The draw back to a 360 head on a teen is not only the larger chamber decreaseing the comp. ratio even further but also ports to large to make effective useable power in most applications on the street. Even more so if the pistons are stock in the teen.

Just as far as that goes, in my application. I have milled J's. 56cc chambers, block was not decked, just plain replacement cast flat-tops and i'm turning 9.7:1 compression. Heads/intake the previous owner had the intake milled to the heads and not vise-versa. (if you mill the heads, mill the intake face, not the intake)
