Ite guys I was going through the junkyard today and found a 351 fi engine that was all intact, the thing is my heads are in need of some over hauling, they need valve seals and possibly guides. What all is invloved in swapping the heads parts wise, would I make more power with these heads with minor porting? My e7's have a 3 angle valve job right now and with the e-cam the sucker pulls like crazy.

thanks josh

351 heads are just as miserable, you will need some head bolt inserts or stepped head bolts since the 351 uses a 1/2 inch head bolt as opposed to a 7/16 on the 302.
