What parts are interchangeable between 302 and 351w?
What parts are interchangeable between 302 and 351w?
302 heads are basically the same as the 351w heads with the exception of the head bolt diameter. 302 heads have a 7/16” head bolt hole and the 351w has a ½” head bolt. Opening the holes can be done by hand, if done with care.
What’s the difference between 302 and 351 Windsors?
But the difference are the bolt size on a 351 windsors are 1/2″ and they are 7/16 on 289/302…late model heads have 1.78 intake & 1.46 exhuast valves and early ones have 1.84 & 1.54 & also slightly larger intake and exhaust runners. Ford began using the same basic head casting for both the 302 and 351W in 1977.
Do you need to drill hole for head gasket on 351 Windsor?
You do sometimes need to drill out the steam pocket relief holes (there the real small holes you see on the head gasket) in either the block or head when swapping between 302 and 351 windsor parts. You use the head gasket as a guide.
Do you need headers for a 351 or a 302?
you’d need headers for the 302. They’re designed to be in the right location for a 302, a 351 head would be higher & out a little from where it would be on a 302. i would say you would need 302 headers because the difference in deck height is what gives you a different angle on the exhaust side of the head.
What are the intake gaskets on a Ford 302?
Also, the late model 302/351 heads have a larger water passage at the rear, which means the intake gaskets are different between early and late models. If you swap “real” ’69-’76 351W heads onto a 302 you need to use the 351W style intake manifold gaskets, as the 302 gaskets will leak water at the unique 351W intake manifold water ports.

What kind of gaskets do Ford 302 / 351W use?
Cometic Ford 302/351W Cylinder Head Gaskets. Cometic Multilayer Steel (MLS) Gaskets are designed to provide the best possible seal for naturally-aspirated, boosted, or nitrous-fed engines. The head gaskets are made from 3-5 layers of spring stainless steel, offering a stronger base material than standard cylinder head gaskets.

Can A 351W head be used on a 302?
The 351W heads will bolt right on. You use the 302 intake. There are some things that you will have to address, though. The 351w heads use 1/2″ head bolts vs the 302 which uses slightly smaller 7/16″ bolts.
