Is my ring gap too large?

Agree. It will be fine.

But understand there is a reason that the gap is wider than spec. Likely, the bore is larger than spec, buy about 0.003". Your piston to wall is probably 0.005 - 0.006", verses 0.002 - 0.0025". Not a problem with your forged pistons, and good on a performance application where you don't want to give up anything. But you're pistons will be rattling around when cold.
