Thanks for the quick reply! I want the engine 100% factory correct so that's why I'm wondering about the cork or rubber foam gasket.
The best sealing will come from using silicone sealant at each end but sounds like you want to be able to "see" the gaskets. Back in 65 I would assume they only used cork then later down the road came rubber gaskets. So cork is my final answer. lol
The end gaskets were cork from the factory on every 64 or 65 273 I ever worked on. There were several times I used something else so I may have a set of the cork ones in the garage. I'll dig around and let you know.
check out his build thread
it is quite impressive
I know that your trying to make the car perfect, but, even not 100% perfect,
they are a very nice car.
How about not worrying about the stuff nobody can see, and drive the car.
Do you have some photos of the car to share with us.?
