Will h23a1 pistons fit onto h22a rods and go into the block . I know the compression is going to be 9:1 but that is what im going for.

 

So your question is in regards to putting H23 pistons on H22A rods, H22A crank, H22A block, with an H22 head on it? If so, don't assume that your compression will be 9.0:1. 9.0:1 is the compression in a completely different setup. You are changing a lot of those variables.
