Well while the engine sits on the stand i sit here seriously considering a mod most easily installed with the engine out of frame the question is which one? Cam or rockers? If it were rockers id be going 1.9 so i dont have to do a bunch of head work. If a cam itd be an S1X. Give me your votes and reasons why. Also those with one or the other please specify which u have and please include what all other things u suggest changing at the same time to maintain reliability. This is going to be a decision made by tomorrow. One the other or neither. So any help is greatly appreciated.
