i heard that the 5.0 explorers had a version of the gt-40 heads, the gt-40p's is this true? and would they work on a '78 351w? thanks for the help guys

it tis true. 97s up had the gt-40ps. they require special headers because of revised spark plug location. mountaineers have them too.

And those special headers may prove impossible to find for a 351. Also, you'd have to enlarge the head bolt holes 'cuz 302's use smaller head bolts than 351's

i've heard of ppl using 'shortie' spark plugs to clear with some headers. that and 90* angle boots. some of the primaries may need to be 'dinged' if you still go the header route. i kinda missed the 351 part. oops. sorries.

I believe all the stock Ford heads are drilled for 1/2" bolts so they should bolt on a 351 no prob. I'm 99% sure the 5.0s use a shouldered 7/16" bolt with these heads...
