i'm sure this would be extremly complicated but someones got to know if there is a way to mathmatticaly calculate piston to valve clearence knowing all the different variables (vector dynamics..??) something i was just curious because i doubt companies like skunk make cam profiles without using computer modeling to decide if they will or will not hit pistons.... does anyone catch what im saying if so please chime in.

 

1/2 the stroke+rod lenght+comp. height on your piston,subtract that from the deck height and that is how far your piston is sitting in the hole.
now take that # and add the thickest of the head gasket and that will give you the ptvc.

example stroke is 3.740"95mm" 1/2 of that is 1.870 now add your rod lenght say it is 5.275 "134mm"
and your compression height on your piston,say it is 1.180

add them together and you have 8.325
now take your deck height 8.340
and subtract 8.325 and that is how far your piston is setting in the hole.which would be 0.015 add the gasket thickness 0.028 and you have 0.043 piston to valve clearance.

i hoped this has helped you

 

but you should clay check everything to be sure,some times the numbers will be wrong,sorry for got to mention that.
