How Much Was Removed?

How Much Was Removed?
Pix of before and after. Now can't line up valley pan and intake. So looking at combustion chambers, and space between valves and edge of combustion chamber. Seem like more than a few 1000ths was removed.....
But I measured the side of the head, and the new spec is 62.56 mm, and I make it about 62.5ish.
Anyone have some heads on the bench you can compare?
Any thoughts to the reduced height and valve interference? I have bumped the starter once since heads put back on and torqued. Did not seem to make a normal cranking sound, more like starter spinning and nothing happening, was not able to see valves up/down.
So if the clearance is too tight, and I have cranked motor, have I now bent all my valves?
This is rapidly becoming the head gasket job from hell.

Here's some more pix. Certainly plenty of carbon, and closer view of logo shows the HGs were Rover (the log is backwards on the imprint on the head). So don't know if the heads were mchined before I bought truck.
But these pix sure make that stuff look "3D". Maybe just bodacious buildup. Lots of miles on cheap gas.
