piston to valve clearance problem.
Stock GSR with a skunk2 stage 1. camshaft.
Dont know if this is even an issue.
Please advice.

the area with the most area of concern is your exhaust
valves. they close later after TDC than the GSR cams
no doubt:
GSR 7deg after TDC at dead 0
ITR 10deg after TDC at dead 0
SS1 16deg after TDC at dead 0 , estimated based on duration spec of 249
a strict engine builder type would say, dude clay check the thing:
if you can do it its the best way to tell,

if you cant do that, well... you will never really know!
not the easiest thing to do... but hey wouldnt you like
to know!
the skunk2 cam gear if this is the one you have, keep in
mind that the markings are 2 degrees on the crank, this
is important. +4 on the gear would be +8 at the crank.
I would contact skunk directly and ask.

no worries dude... also thats a pretty big overlap period
over the CTR, like 35... I would go with a thinner head
gasket to get your compression up a bit more. you will
see a benefit for sure.
