Valve to Piston clearance on LS/VTEC

OKAY this is what i got. LS block, CTR pistons, TODA Spec C camshafts and valve springs. My question is will I have enough Valve to piston clearance with the TODA cams having so much lift on them?????

I still have 1st gen. b16a, but will tell you that with a Portflow head milled .030 and ITR cams I actually was hitting the bottom of my SPARKPLUGS!! and had to switch to a Legend plug.

I am running CTR pistons and CR is about 11.3:1

Am thinking about going to LS/VTEC but scared to keep those pistons with that head with sim . thoughts as you...

I believe I've seen the same set up as yours only with jun 3s instead. I don't believe they had any clearance issues.

But I'm not 100% sure on this one. Tell you what, you try it and tell us what happened.
