are the 351W the same?

[Fostang]

I know there are differences in compression ratios, pedestal mount heads and roller blocks.

What I'm mainly concerned is do all 351w engines come from the factory with 1.84 1.54 valves throught out the years?? 69' 85' 92'??

the later 351's (78-up i believe) had the smaller valves that the 302's had

Or was 75 the last year?

I have a set of 77's in the garage with small valves.

only the "wf" heads had the big vavles and ports on them.

WTF is a wf head? Sorry, had to.

 

[Lswhat]

the heads have wf for windsor foundry where they were made i guess cast in to the heads on top. i really think all windsors were made in windsor but what thats what mustang and fords said. they also said short of hipo heads they are the best factory heads to go to for early models that dont convert.

The 78 and later 351W heads are the same castings and valves as the 302's. The 69-74 heads are the small chambered bigger valve heads, the 75-77 heads also had the big valves as I understand, but larger chambers. Fostang--- if you're looking for a set of the early Windsor heads, I've got two sets to sell. Both are cleaned and mag'd, no cracks, never reworked. Both sets are the D0OE-C heads.
