That's exactly what the shop said that they were going to make sure they'd checked for. I figured it was best to let the pros have the head, piston and replacment cylinder to make sure everything matches so there is no a surprises come assembly time. BTW the prior owner overbored the cylinder and it was too big for the Wiseco 66mm piston by 10 thsnds. You could of driven a truck through the ring end gap!
Thanks for the help guys.

If you have the old gaskets you can assemble the top end and do the check, if the quench is not correct nothing is loss except some time and you saved the new gaskets for final assembly.
You can also measure the deck height of the piston in the cylinder using no base gasket, here are my last numbers on a 97 engine (three layer metal head gasket):
deck height no base gasket minus 0.012
Compressed base gasket est 0.018
Compressed head gasket est 0.045
calculated quench band 0.051
Measured Squish band with solder after assembly @ 0.051” (I got lucky).
