Default CTR pistons with ITR valves in LS/vtec...?

Is there enough piston clearance in ls/vtec with CTR pistons for ITR valves? Is it safe to run ITR valves in this setup?

valve diameter is no different, valve reliefs on pistons are deep enough. so YES.

Simply Just make sure to run 92 octane and check for pinging cause with the B16 head you should be running around 12:2 comp with Gsr around 12:5 with no milling and stock Ls head gasket
