I have a shop filled with about 10 engines and everytime I need to replace a part I just grab a part....never give much thought as to performance or engine year.....engines always start up.....if you dig deep on the web you will find the rings.....but the best thing to do is invest in an 836kit and decide on the best sprocket combination and you will be rolling strong.
