Thread: Good heads for a 351-W

Tweet

I will look into them,I went to a all Ford swapmeet today to see what I could find but found a bunch of 289 and 302 heads plus two overpriced sets of 69 351-W heads. Jeff

Unless you can find a set of really nice DO0E heads, or better, a set of GT40P's out of a 5.0 Explorer, you will be paying a LOT for a good rebuild and probably quickly exceed the price of a set of after market aluminum. Most of the OEM cast iron heads have badly worn valve guides and of course the valve are also worn so need replacement. And then a set of rocker arms because they are grooved, but then the studs are also bent or worn, so you need to pull them and install screw ins. Oh - and the springs have 100K miles on 'em so need replacement. The retainers and locks - oh he!!, might just as well replace them too. It's "only" a few bucks more. When you take a look, most of these heads are pre lead free gas so the seats are shot and need replacement. Oops - they are warped and need to be milled. A pair of $50 swap meet heads can quickly become a $1200++ drain to your wallet - unless you are really lucky

there was a 351 5.8 motor that was put in mustangs in the late 80s early 90s.... good luck finding a head though.... they were very limited production.... i knew a guy that had on..... it was the only time i've seen a ford 5.8 badge

"Very limited production head"???
You do know that the 351 W heads will fit on a 302???

different chamber sizes though..... the 351 is a larger chamber head than the 302........ i guess maybe on a lower compression 302 it might be the same chamber size as a 351..... but the 5.8 HO motors themselves were a limited motor
