ok guys i really need help bad. I have a b18a1 with b16 valve springs and jg regrinds dont kno wat kind. I think i might shoot nos not sure yet though. My block right now is messup cuz i guess the pistons dont fit well or i have fried piston rings cause i cant drive it so much smoke. Should i keep the b16 pistons or put back the stock. And does b16 piston fit right in????
