360 heads on 318

Usually cylinder head flow is more important than compression. However, IMO, 360 heads on an already low compression 318 make it dismal. It will be down in the 7s for compression.

With the mild build you are talking about, I would want the extra compression the 318 heads offer, because you will not be coming close to flowing what they are capable of, much less the 360 heads.

Again, just my opinion of course.
