Can't remember where I saw or heard it, but it was stated that early 351 Windsor exhaust valves will fit Y-Blks & have slightly oversize, 1.54" heads. Is that correct? And what defines "early" engines. Thanks.

Yes, the C heads on my spare 292 have 1.84 and 1.54 351W valves. I didn't fit them, they were in the heads when i got the engine.

Mctim has a youtube video installing windsor valves. I would think that early would mean 68 or 9 those were the first years for the 351 windsors

The intakes wouldn't help me as my spare heads are ECZ-G's. I haven't disassembled them yet, but the thought occurred to me that if the exhaust valves are really old, it might be an idea to replace them with the Windsor exhausts. I won't be building high rpm heads, so I don't really feel the need to spring for imported (to Canada) stainless parts.I'll look further to confirm what are "early" Windsor exhaust valves. Thanks for the replies.

Paul, my book shows '69-'74 351 W valves to be the early ones. They are indeed 1.54 diameter, same stem size, and .020 shorter. I don't know about the keeper groove placement. When I put the 429 valves in my heads I had to cut new grooves closer to the valve tips.

I had an exhaust valve break in a 352 i did a ring and bearing rebuild on that wasnt high rpm either. It was a shame the engine really ran nice and another measly couple hundred bucks would have kept it around. The engine had the comp 268 cam with a 600 holley port matched heads and intake. With a 3.50 gear it moved the 63 country squire it was in quite well,16.7 at the 1/4 mile. Point i'm making is after that lesson i replace all the valves no question

John: Thanks for the early Windsor exhaust valve manufacturing dates. I'm going to try to find Mctim's video on the subject.. Also, if I recall correctly ( thats certainly not guaranteed) a buddy of mine years ago, used 368 Lincoln exhaust valves in Y-blk heads. But I seem to recall that they were a fair amount to long, which may have resulted in valve train geometry problems..??

Paul

Paul, my book (NAPA June '78) does not list any 368 valves available then, so I looked up 317/330 truck valves, they are almost .200 longer than Y valves. I seem to remember years ago some one "shortened and re-grooved" Lincoln valves for a Y according to a magazine article of the time period. Possibly Karol Miller????
