head hunter

StrokerMike, I'm attaching link to the buildup you are speaking of. Pay close attention to the last two paragraphs of the article. I just installed a set of 302 heads to my 318, as well as a Compcam XE268 with springs, timing chain&gear, etc.. I had originally purchased a freshened set of 915 J heads ready to bolt on, but after doing considerable research for over three months, and reading this article and talking to people in the know, I switched off to the 302s. Contrary to Flyfish's results, each and every person I spoke with said to go with either the 302s or magnums. Most thinking is that the port velosity of the 302s with some mild porting(gasket match,etc) will outflow and perform better than the larger port 360 type heads, and this improvement will be where you need it most, bottom end up thru the high 5s. If you plan to run constantly higher rpms than that, up in the high sixes plus, you really should consider another block other than the 318. Check this link. Proof is in the pudding. JMO, Mike
