P90A head what can i use it for

ok so i had this head that a machine shop botched and to level it out it was shave by a bit (by another shop). im not sure about how i can use these mesurments to see what the haed is still good for.. anyways on the under side of the head next to each pair of valves it reads .034 i believe it was the amount shaven off ..???
its a fully rebuilt head so id like to make use of it or possibly sell it..
can any one help..

.034 is etched in or stamped?

Have you tried asking the shop what it means?

1mm = 0.039369091in

I would assume .034 would be the amount shaved off, since the valves are 44 & 36mm and the combustion chamber should be around 53.6cc. I don't know why it would be written inside all 6 cylinders though...

You can machine up to ~.080 before needing shims.

And if you are sitting on your thumbs at work, why wait until tomorrow to call?

cc the head then plug the numbers into the ozdat L series engine calculator. That way you'll know what compression you'll be running.
