have you got more specs ( the more the better.. stroke/CR/etc etc preferably flow numbers or even better dyno numbers) i could run it through pipemax and see what it spits out. it's pretty accurate most of the time.
That sir, is not rust, it is the progressive mass reduction system

I also need valve and stem diameters, cam timing numbers (and rocker or followers ratio if any) and lift.

Thanks yeah clearly the valve size above is wrong.. I blame the cut and paste on the iPhone. :)
