John, Ricky already has Stage III NRHS heads and NRHS 1250 kit. Ricky, I would go with the 45, hence why I'm switching to a 45 when I do my motor build, hopefully this winter while there's snow on the ground in Colorado. | ||

what are the differences between the two, install wise? i need a different manifold right? | ||

Yes, you need a different manifold and carb adapter for the the Mik 45. Both will need the A/C adapter if you plan to use your existing unit. From what I've read of people who have had both on high-end 1250s like yours, the Mik 45 gets better mileage and responsiveness than the 42, and supports more power than the 42. |
