The z3 head was the right choice, z1 is the same as a2 with the water port on the front of the head and not the side. The z3 head is only a few cfm behind the PRB type s casting.Texasnick. The k24a1 head can be ported to flow a rediculous amount of air. the K24A1 head (crv) has the same port profile as a Type S head so it is a good base to start with. If you have the a4 head and want to use that, it may cost a few more $$ to do the head work to it but the results could be better in the end.Yes it will match up to your tranny perfectly. Though since it will sit higher you might need a modded header or a used skunk 2 megapower header which fits K20 / K24 engines builds. If you don't want to look for a K24 block talk to KMOD Performance....or go to their site. They can sell you any block in perfect condition, add the new forged ....
