Correct Pistons??? 1982 924NA

[GLASEM]

Been having an interesting debate about whether or not these are the correct pistons for an 1982 924NA with my engine rebuilder:

Offer your opinion......these have been in the car since 1982
Porsche make a mistake???





Also.......at TDC.......is the 924NA piston top flush with the block deck??? or is it a few mm below?

Have a similar thread on 924.org but am not savvy enough to post the pictures
