Speedmaster intake porting. Hopefully I can make something out of this

Idk how old it is. It was a trade deal that was good for both of us. This carb has 2 1/8 throttle blades. A 1050 and 1150 have 2 inch blades. I suppose a smaller carb may help but maybe not. I don’t want to be cutting, welding and grinding for a few extra horses. This engine is a 543 11-1 compression. .625 lift solid roller. Kim
