    Think dyno numbers are easily manipulated? I will try to get some data together, but the majority of our clients buy from us based on race proven results and actual peak numbers/powerband that surpassed anything they could hit before our heads (including other 'built' heads)

    I do not doubt whatsoever I'm more curious as to what can be gained on the S54 head.
