Yes, the SR16 cams have slightly bigger lobes than the 20VE, say +.4mm IN and +.7mm EX. But, if you are talking about the piston valve relief depth, then no the SR16 valve relief is not deeper than the 20VE. You would think the valve lift would match up with piston valve relief depth but they don’t. Take for example the 20V cams, they have even higher lift than the SR16 yet the 20V piston valve relief is shallower than the 20VE.
If you are running the SR16 cams with the SR16 piston, I wouldn’t worry about the piston to valve clearance. However, with N1 or bigger cams, I would definitely check the piston to valve clearance.
IMO, the SR16 pistons are not that strong. I saw first hand the results of running them in a build similar to yours. All four pistons crack their ring lands on the intake side, pretty shocking. The engine was running 13.5:1 compression ratio on 91 octane.
Based on pics, I think you have enough skill to measure and find out for yourself. When building an engine measure everything for yourself. Don't go off on assumptions from the board. Be careful there are some guys on this board and all they do is regurgitate bad info, no firsthand experiences.
