Forgive me for being blunt and crass.......
But I'm not sure why you ask for help when you head 180° from any advice given.
*Rod bolts need to be pressed in and the rods need to be resized. Anything that is off .001" is not good enough.
*Don't add head gasket thickness to correct a compression ratio issue.
*Don't use Cometics on a block/head that don't have the proper surface finish.
A correctly chosen camshaft would have given you the powerband you wanted and can be chosen to work with a higher compression ratio. Buying a random camshaft, then retarding it to crutch compression ratio issues can quickly get you an engine that's not in the least bit optimal.
You may quickly end up with an engine that leaks from the head gaskets, has detonation issues because of high compression/large quench, and wears bearings because rod bores are out of round.
We are trying to help steer you in the correct direction.
BTW, from your other thread, the keyways on a crankshaft gear have their own corresponding dots on the crank gear.
