Are my compression test readings sky high?

D16a6 motor, ZC head, metal Z6 headgasket. This was my compression across the board. Just removed the #15 fuse, cranked the motor and went WOT and got these readings.

Too high? Did something wrong? 200+ across all four cylinders. Motor has 115K miles on it.

you might have some carbon build up try using some seafoam to clean it out and check numbers again...

when i had the head off in december there was very little carbon buildup on the piston heads...i did scrape off a little bit with my finger but it was nothing really too bad.
