225 connecting rods

Bore is .060. The block is bored, honed and decked .040. The pistons are .018 shorter than the original's. So I tried to make up the difference and then some by decking the block. It had a decent std bore but the guy I bought everything from bought .060 pistons, wich looks not to be a problem in the slant. I'll mock everything up when I get it back and will know more for sure then.

Is the combustion chambers around 60cc? I think I read that some where. The head will be next. Just replacing stock size valves and maybe La valve springs.
