I have a h22a closed deck block and need a headgasket for it. I honestly dont know what year the block is and dont really know how to find out. I am new to h22's, but from what i think i know.. the h22a1 was also closed deck. I got a headgasket for a h22a1 but it is completely different. The block i have has 2 long oil returns on each end of the block. The headgasket has 2 longs ones on one end and 2 smaller ones on the other end. I did a little bit of searching on here but really came across no information. Any know what im dealing with?
