heads... exhaust... intake

Alrighty well. The 360 manifolds i think 360 heads have bigger exh ports than a 318? but im not sure. If so then they would be a little better to use than the stockers. As far as running the heads, 360 heads are a pretty common thing for 318 upgrades, 302 and magnum heads as well. Downside to the 360 heads is that if you bolt them on, you will have low compression ratio. They will need milling to raise the compression ratio back up.

I have stock, milled j-heads on mine. 284rwhp S.A.E
