Please identify those pistons

[hbrand]

1.) This is a 2.0 piston




2.) This piston is in my 1973 911 unknown size.

Measure across the bore
2.0 is 80mm
2.2/24 is 84mm
The valve relief for a 2.4 are too deep for even the S for 72/73.

Can't measure the 73 engine piston, engine is still running great.
Picture done with bore scope.

Take a look at this thread for comparison pics of 2.4 pistons. I would guess 2.4E.
