318 with 360 heads and compcam build help

I'm sure that milling those 360 in order to raise the compression ratio has been brought up. Wouldn't raising the compression ratio along with more air flow require more attention to tuning?? Also doesn't milling the heads affect the valve train geometry and push rod length which would affect lifter preload,correct? I don't know the amount that needs to be milled from the intake side of the cylinder head for every 0.010" that's milled from the heads in order to retain intake port alignment, having the block decked and running thinner head gaskets can affect the valve train geometry too, and intake port alignment. I've heard the China wall sometimes has to be milled as well especially when the heads / deck surfaces have both been milled, I couldn't find what the amount milled is done before the China wall needs to be milled. What I posted above has been mentioned by other members on different threads. I'm not saying that 360 heads don't improve the performance of a 318 I'm saying that there's more involved than just having them milled on bolting them to your 318. I believe that 318willrun has used 360 heads on a 318 and had good luck in doing so, my questions deal with the milling of the heads 0.030" plus.
