Been shopping for rebuild parts for my late (year unknown) V8. I notice that 2 different valve part numbers are listed by some vendors (8ba-6505&1ba-6505).
Is this due to the use of valve rotators on some engines? How are they different? I assumed the height of the rotators was made up in spring length.
Keeper grooves in a different spot too?
My engine has the rotators and I planned on re-using them, so which valves do I need?

If your looking for exhaust valves, why not use SBC valves. Their common as dirt, cheap and are hardened for use with lead free fuel. My friend had a head shop and he gave me 8 of them for nothing.
They last for 200K miles in cars and trucks, so they will last the lifetime of a flathead.

Yes, the 1BA valves and related parts are for the rotators. The highlighted valves should be correct.

Thanks Ross, i think I get it now.

I went back and looked at my old valves...seems there were at least 3 different styles in there! Combined with the weak springs it's a wonder it ran as good as it did.
