Hey guys, I need a little help. I have a friend who has an 08 F-150 with a 2V 4.6 in it. I don't think they switched to the 3V until 09. I am going to help him put new heads on it in a couple months when he gets back from basic training. I have done a few PI head and motor swaps into mustangs, so I'm very familiar with the 4.6. I would assume that since it's an 08, it is basically a PI motor from the mustangs, so the PI heads should swap right on the bottom end, but I wanted to ask first. Thanks in advance for any help.
