351 heads on a 302

[ken]

Fellow EB Bronco fans,

Question-

I've heard that you can install 351 heads on a 302 motor.

What could one expect from this mod.?

And-

Are there any issues with headers or aftermarket intake manifolds? Your thougts please....

Thanks,

ken

They are pretty much the same head only real difference beside valve size in some is the head bolt size a 302 has 7/16 bolts and a 351 has 1/2 . I have a set of 1986 ** 5.0 heads on my 351 and all I did was drill the holes out to 1/2 inch . No difference in intakes or exhaust /emoticons/[email protected] 2x" width="20" height="20" />
