Ok, 318 cu in, First year for roller cam, were the heads small ports? Wanting to do an aluminum intake and TQ, got two Eddys one is a sp2p or something like that, small runners. Other is a performer says 318-360. What should I use? No race truck just hot driver and I do have a set of fresh late 360 heads I could use. Cam will be reground to a little better profile.
