Default What part numbers?
Does anyone have the GM part numbers for the intake and exhaust valve stem seals?

I got 12564852 for the exhaust and I think that is correct, but please correct me if im wrong.

I also had 10212810 for the intake but when i put it into gmpartsdirect it said lt4. Is that the correct part or doe the lt4 heads use a different intake seal?
