I am currently rebuilding my 993 engine with new p&c's (Je Pistons and Nickies) During the normal measurement process I put cylinders 1 and 4 in place to measure the deck height, and ended up with #1 at 0.681 mm and #4 at 0.899 mm

When the difference was so large I ended up installing the rest of the cylinders with the following results:

#1 - 0.681
#2 - 0.732
#3 - 0.758
#4 - 0.899
#5 - 0.792
#6 - 0.790

All measurements are in mm and were done with a dial gauge on a height measurement bridge.

What sort of options do I have to get these back in line, as the 993's don't use a cylinder base gasket?

Any help, direction or chastising is appreciated.
