I'm rebuilding a '59 292 from a Edsel Ranger. It's bored 30 over.

I'm using the original cam with new bearings.
What is acceptable cam end play? How is it adjusted if it is too loose?

New 30 over pistons with Sealed Power rings (9113KX ,030)
These are not grind to fit rings (or are all rings?)

All top ring gaps are between 0.19 and 0.21
All second ring gaps are all between .014 and .015.

Shouldn't the second ring gap be a little bigger than the top to prevent piston flutter?
Do I need to grind all the second rings to something like .023?
