Thread: 302W with 351W heads

Tweet

Pat that engine just looks so mean and even with out hearing it at all .

Hmmm- Pat, that 351 of yours would just fit in my '31 and bolt right in place, even the C4 would work except I would have to change intakes to get the hood back on.

Now back to the question - the 351W heads will work on the 302W/5.0 though you do need to bush the 1/2" bolt holes to 7/16" (Summit sells the bushings, ~50 bucks). The 302W needs a 221-302W intake - an Edelbrock Performer or Performer RPM both work well. They also have a 2bbl intake as well if that's you thing, but it is a race type Victor, not well suited for a DD. There are 351W heads that are junk and good ones, with the best being the D0OE. They too need some help, like screw in rocker studs and the exhaust ports cleaned up by removing the EGR hump. They will probably need new valve guides as these vintage Fords wore them elliptically. So with that said, and by the time you have stock heads rebuilt, you meet or exceed the cost of a low end set of aluminum heads. A good iron head would be the late '90s Explorer/Expedition GT40P's if you can find a low mileage set. If not, you will spend as much to rebuild as those cheap 351W's.
