You described building an engine and then mentioned two engines. Both are going to be rebuilt so, start with the cheaper one? You need the crank and block to be good. You are going to be replacing the pistons, boring the cylinders, and putting forged Chinese rods in it.

You should be having the head cleaned up, the valve guides checked, the valves done, and new stronger springs put in it.

I don't understand the interest in higher static compression ratio because it will hurt your ability to run optimal spark timing, but whatever you want to do. If you run a quarter PSI more you will more than make up the difference and be able to use a superior spark timing map. You will also have headroom for when your goals change, rather than being artificially limited.
