Need non rotator exhaust valves for a 360

Anybody have a parts listing for non rotator exhaust valves for 360 heads. I want to use 340 valve springs.

when did valves start rotating ?

All you need is a set of 8 regular retainers getting rid of the rotators and 8 regular length springs. Valves are fine.

The difference in the valve length isn't huge. I think about .060. If this is a mild build and single springs I wouldnt worry about it. If this is a race effort, I'd suggest using stainless nail head valves anyway.
