You will have to install a cylinder head and find out. There are threads on here on how to measure it.

It much better to check it now than have to tear it down later.There's this word called regret that rolls around my beer soaked mind.Now Ive read that .030 to .080 are mins. for intake but if your around .060 all would be good. Exhaust is more some where around .0110. Im remembering this now you should check for sure though.
