Ok so my crank on my jdm h22 is too messed up to be machined and I need a new block, and all the blocks I can find are usdm. So my question is if I transfer the pistons to the usdm block is there any reason why it wouldnt not function correctly with the jdm head? i.e. compression, clearance and anything else. Thanks again you guys are always helpful

 

iirc they are the same

 

are you sure? somebody i know tried doing that and something, cant remember what, didnt work right.
