I'd stay clear of the 200 hp levels. Ring end gap was 'likely' not gapped that wide, assuming the builder didn't have NOS in mind when the engine was assembled. It was recommended by my man to not go passed the 185 hp shot. Mine happens to be the NOS system: 150, 185, 210, and 250 hp levels. The more you spray, the higher the cylinder pressures and temps go. Butting the ring ends would spell dissaster. Play it safe. A 150 shot knocked 8/10 ths off my et on a bad day and gained me 8 MPH at the end. Your difference could be more.
