Default Serdi 100 Pontiac d port pilot size

Hi everybody. I was wondering if anyone knew the pilot size for an intake and exhaust pilot size for d ports. Save me some time. I’m on the hook to buy my pal the bits to help me out. We’re using a serdi 100. Thanks in advance

iirc

.342-to ~.344 - 11/32 pilots

at least for the old Black and Decker seat grinder stone sets

i am sure someone will be along shortly that can state for sure

ps. if he has the pilots for early SBC he may already have what is needed.

The only Pontiac head that did not have 11/32” stem valves ironically was the highest performance motor, the RAV with its big 3/8” stem valves!

I still can’t figure that one out, I guess they thought being like BB chevy’s and BB and SB Mopar’s was the way to go?
