5.0 heads on a 351w?

far as i know they do. someone correct me if I am wrong but that is about the only thing that does cross over. It is wider on top where the intake is and taller in general but the heads are the same. someone else chime in please. the only experience I have is a friend had some aluminum edelbrocks he was going to put on a 351w but i bought them b4 he was ready to put it in.

Yes they will swap over, same goes for 351W heads on a 302.... A stock 302/5.0 head is way to small for a 351W though..

A 302 head will only fit on a 351W if you drill the head bolt holes out to 1/2" from the stock 7/16".

A 351 head will fit on a 302 if you use the stepped head bolts/studs or the t-washers that convert from a 1/2" hole to a 7/16".
