Cam for a 360 build with the parts i have

How do u plan on getting 10-1 or 10.5-1 with out getting into the short block? Kim

can Auzdart tell us what pistons he has and how far below deck they are?
the RHS heads are probably 62-64cc combustion chambers?

I plan to use the bottom end that is already there. It has been rebuilt in the past.
I have on the shelf a new set of RHS heads & air gap manifold which I want to use.
