    Hi there,

    where did you get the work done on the head? how much?
    I would say 170/180 BHP with a good live mapping.

    I'd agree with the lower to middle of that figure with those cams, 185bhp is what you'd expect to see with bigger inlet valves & more aggressive cams like catcams 213's or Piper 285's

    I did the porting myself.

    Lets hope I didn't opened it too much.

    The exhaust ports passed from 33mm to 40mm.
