A guy in town here has a 78 Lil Red. He swears up and down that his truck had W2 heads on it. Took them in for a rebuild and got a different set of heads back. He said the machine shop screwed him over. Kim

Pretty easy to prove if so . His intake wouldnt have bolted back on and his rockers/ pushrods would be wrong.
