Ok, so I’ve found a few threads with the opposite swap but I haven’t clearly found the answers I’m seeking.

We have a P13 head from a Jdm H23A that has been built(BC Dual Valve Springs, Retainers, and keepers, and stage 2 Skunk2 cams. My questions are, will the head bolt on the H22a4 block and be compatible. And if so what all needs to be swapped from either to make this work. I still have all the parts to both engines like timing gears ect, just wanna make sure what and what not to use.

Any info would be much appreciated as well as links to any threads that I may have missed for this exact subject.
