0.462 int./0.470 exh. lift

I calculated that with the 1.6 rockers my lift will be: 0.493 int. / 0.501

For springs I'm not sure. I need to ask the engine builder. I believe he said around 120 seat pressure and 320 open.


i have always read that pro comp stuff were junk. I've been told the PRW are not so bad....?
