Valve stem wise, yes they are both 11/32” / .341”, guide OD wise you need to tell me/ us if the guide has been cut down from stock to .530” or .500” seals,

Where is here you speak off?
It’s not a matter of looking at the seals, you need to measure the OD of the tops of the valve guides!

Please note that if the heads are still stock that neither the .530" or the .500" seal I posted about will work, as the tops of the guides will have had to be cut for them.
If the heads are staying stock and running the stock original valves then the seals your buddy needs are the small O-ring type seals that load into the second groove on the valve stems once the retainer has been put on. I just looked at the Summit racing site and they have all three of what you might need in stock. They have the comp Cams rubber O rings. They have the comp camps Blue .530" guide seals . They have the comp Cams .500" guide seals. All of these they have multiples of in stock. Note that if the positive guide located seals are used that the stock Round oil shield that goes over the top of the valve spring should not be used anymore. The removal of these calls for the use of a .030" valve spring to get the lossed seat pressure back.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world.
