4.6 block, which gaskets?
Hey everyone, so I'm putting a 4.6 into the defender, retaining the 3.9 heads, and timing cover. I take it the head gaskets will be for a 4.6- but will the rest of the gaskets be for a 3.9? Did anyone have any luck ordering through summit for gaskets - by ordering for a buick 215? As for pushrods- any difference in length between the 3.9 & 4.6?
