Did you cut a cross section of that putty to see what the actual clearance is? I use play dough as silly putty can flow a little. You could cut across it with a fresh single edge razor blade and leave 1/2 on the piston and measure with a caliper (or with your eye if it's clearly thick enough).
Sounds great on the valve timing.
So you were using the 210 gasket with 13.5:1 static CR? Wow. No o-rings? I would worry it wouldn't work a second time, and like Rick's idea... I guess you are using head studs and plenty of torque?

I used a slightly different method of measuring the valve pocket distance from the top of the piston with the clay.
First, I measured the "floor of the pocket in a perpendicular plane to the piston top, then I remeasured in the same plane to the putty's edge smashed by the valve and subtracted the difference between the 2 measuremants. It is just within spec for such things.
Yes, using the AP-210 Big Bore Gasket with 13.5:1 with no O-rings. I use ARP Head Studs on all of my builds. No reason not to! Likely was torqued to 100#/Ft. in 3 even steps.( would hafta check my Notes for sure.
I don't mess with stock fasteners for my go-fast stuff.
