I just got an E303 cam for my stock fiveoh. I'm going to be getting new lifters, springs, rockers, and a TF Street intake. Is it feasible to use 1.7 rockers in this setup with the stock heads or do I have to stay with 1.6s? I do plan on getting some Twisted Wedges (or similar) eventually -- will the parts swap over cleanly? Thanks for the help!
