With the torquer cam (1st generation profile) 233\233 .595\.595 112 +2 and the 225 dart heads with 2.02 1.60 size valves is there going to be problem or will I have to notch the stock pistons..
Cam is 113+0 I do think they were milled because when I first ordered them about 2 months ago I asked them to mill them to 11.1 because I was going to run stock head gaskets.After doing some reading 2 weeks later I cancelled the milling and ordered .045 gaskets .I going to call and find out right now.
The clay is not really that great of a method of checking p/v. The head gaskets aren't helping clearance, but I have noticed a difference on valve drop between some of the dart heads. Honestly I think running a stock gasket would be the best bet. We just started using a completely new CNC valve job system that will not only set depths perfect everytime, they will even blend the valve job & cut it with virtually no runout! If you have extra time I would have no problem using the new cnc machine to cut a valvejob on the head & sink those valves a few extra thou to get you some p/v back! 
The standard Stage 2 CNC ported dart heads we ship use Darts valve job.

I turned the motor over by hand and everything went smoothly and didn't hit. I am not sure the exact # and I also have my pistons slightly eyelashed on the intake side do to a lot of over-revin in my last set-up
