Alright, I got an H23 block, crank and prelude type-S pistons. I'm afraid that if I use the H23 rods (which I don't have yet) that they'll stick out of the deck too far and if I use the H22 rods that they won't yield the kind of compression ratio I want. I also want to upgrade to stronger rods so I need to know which size to use. Thanks to everyone for all your help!!
