is this a 351 or 302. the e7 head will get you more power for sure on a 302 if this is a 351 don't bother because the e7 for a 302 is to restrictive as it is

i think e7's will hold you back if they came from a 302 unless you do some porting an pollishing to them. they blow for 302's and would really suck on a 351. go to this site and check out his e7 heads. i bought a set and they flow way better and realy look good. www.thumperoforangepark.com

you also need to drill the holes out on the heads because the head bolts on a 351 are thicker than the 302 head bolts are.

The E5 heads have more restrictive exhaust ports as opposed to the E7's with a larger "thermactor-bumps". Intake ports are the same and I think the combustion chambers are bigger at like 64cc's. Aside from the vintage 351 windsor heads and the gt40's on the fox-chassis cobra, the E7 heads are the best windsor casting. After 1977 351w used the same heads as the 302 eccept for the bigger bolt holes. The e7's will work fine on the 351, they are way better than the E5's.
