12V puller piston options/opinions

Has any one else had problems with the mahles cracking by the bottom ring land?
 
I am looking at using the 286110 piston .020 over. I believe it has a 47.3cc bowl and has a 17.3:1 compression ratio. Would someone be able to figure out what the compression drop would be with a .120 flycut and the head will have larger valves as well.

The 286050 are not in stock so i will now be going with the 286110
 
Thats a good piston, I have be runnin it for years. Thats funny that you guys are just now figuring this out.
 
Had a 24v in the truck before did some damage so im sticking a 12v in the truck. Im just not sure how much a .120 flycut will drop compression.
