Flat Top or Dished Piston

[propain37]

I have a GX160 -haven't taken it apart yet- and I want to know how I can tell if I have a flat top piston or a dished piston. I also want to know if I can figure out if I have a UT1 piston or UT2 piston.

Flat top is a flat top

Dished will be dished. Or it will be sunk down and not flat.

I get it, but how do I figure out the type of piston without taking my engine apart? Cause if I take it apart I'm going to need to need a new head gasket and I don't want to go through that until I'm fully committed.

TDC and look in the spark plug hole... or get a borescope to see inside...
