I hate to necro a thread like this but I think it's worth clarifying since so much good info is here already...

Does this "Supertechs + VVT = Interference engine" thing apply to other compression ratios for the supertechs or only the 8.6:1 pistons specifically mentioned in this thread?

My engine with untouched 11:1 ST pistons, stock VVT head & cam, .020" shave on block, have an interference of about .008" at worst case; valves full open, piston at TDC. I have been running it like this for a couple of years now. If it goes, I get to build a better one!

My setup have contact (counting with the stretch margin at 8krpm) if the cam intake cam advance goes beyond 24 crank degrees.
VVT hickups (overshooting the advance too much) will bend valves...
So it's not only the 8.6:1 with stock valves and stock cam
