can it be done? and what would i have to do to a h22 head with s2 p2's to make this work without clearance issues, and maintain a 12.1:1 compression?

what do you know about the K20z pistons already? bore/comp height/valve size/dome vol... ?

well from what ive gathered its got a 86mm bore, same as a f23, and has the 22mm floating pins, perfect for f23 rods and 11.5:1 comp ratio in the k, but i dont know what that means when it comes to how much they are gonna protrude from the block in a f23. *shrugs* i know i need to flip them 180* due to the k motor being reversed, but im not sure what the valve clearences are gonna be in relation with a h22a1 head, should i be using wiseco stock replacements or flattops? and what sort of head work i actually need to do as far as milling it is concerned, or how im supposed to go about finding that out, without getting kneedeep in the build, i mean theres doing things with hassles and doing things without. im looking to use skunk2 pro3's, but i already own pro2's im willing to settle for, im concerned about the valvefloat im gonna get because of my ultra low boost supercharger, my head is already worked with brian crower valvesprings and farrea flattop valves , with a gasket port, euro r mani &s2 68mmtb, i literally cant find any information on this no matter how much i search, i guess its because no one really cares to do fun **** anymore, they just rather swap in a k, but im a little more complex then that and its starting to bother me.
got any suggestions or helpful advice?

what i know: OE pistons (and probably aftermarket too) will need the valve reliefs enlarged a bit on the "original exhaust side" of the piston.

beyond that you'll need to clay the engine to find out. good rule of thumb whenever you're putting parts from different engines together.
