11 to 1 is pretty high, even if you could cut the pistons (and I doubt that is possible) you couldn't cut enough to drop much compression. Going with a FAT head gasket would help, but again, not "that much". I mean 11 to 1 is WAY up there!

It's likely you'll need new pistons with a stroker anyway. Assuming your piston to deck clearance is typical at or near "zero" a stroked crank will push the piston above the surface of the block. You need to change the piston pin height (compression height). Not to mention valve to piston clearance issues!

I was bummed I had to buy new $800 CUSTOM pistons, but that was the only way to get my compression from 12.5 to 1 down to 9.8 to 1. My "old" Ross pistons are in excellent condition,,,,, hmmmm,,,, maybe e-bay those bad boys!
