but with a sbc valve stem diameter? The stems on these valves are the exact same as sbc. I might have measuered the intake wrong... will have to check tomorrow.

Hi Matt:
The 2.11 or 526102 I think is a pontiac standard purple intake valve for a 77-79 T/A with a 6.6l. It lists that valve as part of the 77-79 W72 Firebird performance package.
I cannot find the other however.
Hope that helps with one , other is probally pontiac also but the number does not jive. Joe
