44815, JE Piston Ring Gap?

Anyone with JE pistons and rings....did you have to file your rings. If so what gap did you file them to on the number 1 ring and on the number 2 ring?

These are for JE rings, but I'm sure the numbers are similar. My machine buildr told me that the rings should come with the appropriate specs as well.

Just did the ring gaps for the JE rings a few days ago. These specs are what JE told me directly after talking with them about my setup. Higher boost needs slightly larger ring gaps(i plan to run quite a bit later on)

Top ring (silver edge ring)- .024 inches
Second ring(dark ring, small dot on ring faces up) .022 inches
Oil control retainer rings(not the oil scraper ring) min of .015 inches.

I didnt have to do anything with the oil rings, they were all in spec when i measured them. Yes, get a fine file and grind down one edge of the ring, keeping the edge as straight and at right angles as possible. Take small increments and check the gap. I pushed the ring with the piston top in the cylinder about a good 1" down. Be SURE the ring is square in the cylinder bore. I'm running the JE 8.8:1 .020 over pistons, and JE rings.
