I have Patriot Performance Stage III heads with 1.84" intake valves and their cams. .545"/.550" 233/237 duration 113LSA. I also have 18cc dished manley pistons. I checked the PTV clearance today and I have .060" intake and over .200" exhaust. I know the tolerance is .080 and .100 on the pushrod motors but is that different on the modulars? Will I be alright with these clearances?

No I believe that .070 and is the minimum and .080 is target. The only real way to do it is to check with a solid lash adjuster and allow for .030 give or take a thousandth for rod stretch. Also they must be degreed.
