40hrs?
We’re talking a mild bowl port job here...... more like 4hrs......... and very worthwhile for a school class project imo.
Interestingly enough, there’s a current thread going on right now over on speedtalk where they tested some unported oe heads against a couple sets of ported versions of the same oe heads on a pump gas(87 octane) 302 Ford with a really small hyd cam.
One set made 50hp more than the unported heads, the other set made 70hp more.
I missed the part about it being a school project. A class on porting techniques I would be interested in attending myself.
I was just replying to the question of, in my opinion "is it worth the time/investment to port a set of cast iron 452 heads?" I was just trying to offer some alternative suggestions that would
increase HP in the simpler form of bolt ons.
As an educational experience, the porting techniques learned first hand would definitely be valueable.
