Hey guys, a friend of mine is puttin a 351 in his '94 and the windsor that he has, has 302 heads on it, and they are turned around backwards (thermactor plugs on the front now) and he and i are wondering if 302 heads offer higher compression over 351 heads???? if the compression is higher, he'll turn the heads back around and continue. any tips are really appreciated:bigthumb

Heads are the same...only difference is that 351 heads use larger head bolts/studs.

No they are not. There are threaded inserts in the smog passage.

Unless, someone has put "other than stock" plugs in there. Not likely though.
