You should definitely verify your valve clearances. Take your time and don't take shortcuts. You may have stock stuff, but once your case and/or heads get machined they are no longer "stock" in terms of dimensions and tolerances, etc.

Also, you should definitely verify clearance at several points before and after TDC as, depending on the cams you have, piston TDC may not be the time when the piston is closest to the valve. Also, if you're getting close to "safe distance" on one piston, you should definitely measure your clearance on all of them.

Also, depending on the piston dome design you have this shallow a deck height may put the domes themselves in danger of contact with the heads.

Might seem like a lot of time and effort, but consider how much effort it'll be if at your first trip to 6000+ the metal bits inside your engine decide to get "overly friendly."

Wayne's book says to shoot for 1.25 - 1.5mm of deck height IIRC, but a search on "deck height" shows that experts like Steve Weiner and Henry Schmidt say shoot for ~1mm because it lowers the detonation potential.
