i have a H23a Doha vetch with a PDE head. I want to know If I can use the H22a clutch and flywheel. And also if I can use H22a head studs. I also cannot find the proper gasket kit for the engine. I have a h22a4 head gasket that will work but I don’t have some of the seals I need o rings for the hard coolant tube on the back of the block and fuel injector bushings/o-rings. If you know if any of the parts of the block and head match up to another H block let me know I’m kind of stuck.
