so my engine build has been truckin along just fine so far. got everything in and started to assemble the motor when it hit me....what should the piston ring gap be?
i bored it to 3.992 (.050 over) and have keith black aluminum pistons in it. but what should i do about the gap? do i go with a factory gap? smaller gap? or larger gap?
thanks guys!

Factory gap will work fine.
