360 build ????s

The pistons have .005 relief in them. When he disassembled the motor the pistons were .003-.004 below the deck. They are not flat tops. We are not sure on the cc of the heads but he said they seem close to what he is putting on his new motor and those are 70cc. Then he figured a .040 blue Felpro gasket. He figured up a 9.92-1 compression ratio. Idk how far down the pistons are, unless you meant below the deck. otherwise I have provided what I do know....

My next thing is. This block needs one cylinder sleeved. Machine shop said there is the risk to warping the next door cylinder when doing so. Thoughts on that route or should I just bore a different block and avoid the sleeving? All in all to get my compression ratio up I have a tally of roughly $1500. That is machine work, cam, gasket kit, high volume oil pump assembly, new rod bolts, buying his pistons/rods and block, new water and fuel pump. Still need to figure up a cost for bearings of course. So I am kind of spun on what to do. It is starting to get to the point of where do I say too much money and go with the 408 out of the gate.
