Well I got a h22a4 in my 5th gen lude non s. it has bad bearings and found a h22a1 with noisy head. I'm gonna put the a4 head on the a1 block. Anyone done this setup and ran into any problems? im gonna have it obd2 so gonna seap sensors onto the block. All ican find are h22a1 heads in h22a4 block thanks

 

Looks like I haut gotta put crank sensor, to in gear and swap the balancing shaft or don't put a belt on. And a h22a4 head gasket right?
