Supertech over sized valves & N1 Cams
Searched and found nothing, anyone running this combo? I would really like to know if there will be any issues with piston to valve clearance when running N1 cams with Supertech over sized valves (+1mm/IN, +2mm/EX).

Stock 20VE bottom end, stock head, stock cam gears.

no reason to run oversized valves.

the gains are minimal, spend your money on pistons or headwork.

Do you have the info to back that up? Don't get me wrong Stratton, but I haven't seen anyone running this combo prove or disprove the minimal gains, as everyone has done with the N1 intake mani, and I still want to know if there will be any clearance issues?

why go with 2 on the exhaust and only 1 on the intake? should do 2 intake 1 exhaust if anything

Because the ve already comes with 1mm smaller exhaust valves than the normal de/det's This is why they did 2mm larger exhaust valves. Intake valves if im not mistaken are the same size as any other sr only exception being the stem size.

This is why supertech did that combo. Where if you look at their combo for the de/det is usually +1, +1 on each.
