Degree numbers for small Webs & 1397

Hello all. What would be some good cam numbers to run on a 13:1 1397 with the small Webs and ported head? Working on a little project. Thanks.

Wow. So I guess I better change from the present setup of 106.5/102.5.

Any advantage to running the exhaust cam that high?

It just pushes the power curve upward.  105/107 works pretty well to. I rode a busa with a 1397, yosh cams with 106/109 and the main grunt of the power was 10k up.  Depends on what you want. I would say 104/106 is the best compromise between midrange and top end power.
