Butler PEP .530 x 11/32”.
When you call ask if they have the proper plastic installation tool for them, if not get one from Summit or Jeg’s.
Be sure to nicely oil up the head of the valve to get them started .

With these seals even if your valves have the second groove on the top for the stock type O-rings do not use them.

I use Lukas engine oil supplement to lube the valve stems before they go in the guides.

Fairly certain you don't want to stretch the valve stem seals over the valve head.

Well yes, they should come with the clear slip on starter guides for the top of the stems.
