Hi. I'm new at this forum but I've been trying to find a lot of info on my h22. I'm thinking of rebuilding it but with type s pistons and I already the code on my block is aaaa but I was wondering if I'm also gonna need type s a type piston rings or if I can use any type of h22 piston rings?

 

Any year H22 rings will work, all use the same part number.
