302 heads

Yes, MP was guilty of pushing the swirled port heads too hard, especially the 302s. the 596 heads have great low lift flow, which is going to make more power than any 318 port head. I believe the last time I checked that the 302 head specs at 58 cc’s, but some measure as high as 61 and as low as 55, depending on what day of the week they were cast and what life was like at home at the time! To give you an idea how good the high swirl 308 and other casting number heads are, I can buy a set of 915J heads from a friend for $100 right now that need refurbished (ona running 318 no less, one sticky exhaust valve), but I am going to scour through his mid eighties truck 360 stuff to see if I can find a set of early small pushrod tube boss or other high swirl 360 heads. I’ll use the J heads if I come up empty on the other search. Low lift flow and superior exhaust ports are what makes these heads.
