im rebuilding my 4.6 after it blew. the block is at the machine shop now getting bored .30 over. i was going to have my npi heads port matched to the pi intake manifold but i think i want to just get a set of pi heads. im going to run a 10:1 piston so w/ pi heads should be 11:1...is that to high? i also want to get the heads ported. would that be pointless if im running the stock pi cam? would i get more power out of a aftermarket cam with the stock pi heads?
4.6 2v rebuild what cam, porting?
