Ask @MOPAROFFICIAL about the 302 heads. He knows a LOT about head flow and I don't think he likes them. IMO you might be messin up a good thing. I like the F150. The money hole in the water, meh. lol
My amazing better half puts up with the old gas guzzlers because I take her out and do stuff like this on the boat! Life is an intricate balance. That boat earns its keep let me tell ya! lol
