I had a timing gear issue which caused my 350 to bend 3 SS exhaust valves.
The ones I find on Summit (Sealed Power V-1770) are the correct dimensions, 1.562 dis,.343 stem and 4.728 lgth, but they are "steel".
Can I use these safely with my SS ones?
Thanks, Frank
Just found out these are stainless........tech guy from Summit looked info up on Fed Moguls website, so I'm good with these.

 

I know this is a few days old but ....... I do not think those are stainless valves. They are listed in the Sealed Power stock replacement catalog. I would call Federal Mogul just to be sure. 800-325-8886

 

Thanks Bill, I went to Fed Moguls site (www.fme-cat.com) and looked up my part, V-1770, it is made of 21-2n which is a stainless material.
