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!
Rockers.. 1.6 or 1.7?

Well don't forget there are two types of heads, pedastal and stud mount heads.. Stock heads are pedastal, I would get stud mount heads because the stud mount rockers are much better when making more power.. Plus you don't have to worry about shimming the rockers to adjust them only have to tighten the nut that holds them down

you should be fine with using 1.7 roller rockers ONLY if you change your springs out, becuase if i remember right an e cam with 1.7s would be into the .540+ lift range, so make sure piston to valve clearance would be fine, talk to a local machine shop
