GT40 Heads Conversion

Howdy folk, doing a GT40 heads swap in my 5.0 94 f150 stock engine. Will my 5.0 intake and exhaust manifolds bolt directly to the Gt40 heads with no modifications? What do I need to swap these heads?

In looking at the same thing, the exhaust manifolds... are a bit of a challenge.

has not yet found a set of reasonable heads. Is still looking.

Yes. Gasket set. Maybe use a pushrod length checker to verify nothing has changed?

The head bolt holes "could be" 1/2" rather than 7/16 which might require either bushing or different head bolts.

The set I pulled of an un-molested 5.0 Explorer had both. To use on my 5.8, I had to have on set drilled to 1/2"

I would invest in a push-rod checker & mock it up to be certain of the length needed.
