cyl heads

Let me preface this by saying I'm not a fan of 302 heads (except in cruisers and tow vehicles).

With a "big cam" they will suck big time (especially with 8.5:1 compression). The ports are tiny, and they are made for efficiency, not power. If you want power, then you will want another head. With a "big cam" you car will be a dog off the line...be prepared to have humble pie served to you by every Camaro and Mustang you see, because it will be slow.

If this is just a cruiser, get a relatively small cam and you should be fine...JMO.
