Port my current M1 single plane or install the RPM Air Gap?

Do you have an aftermarket 5 or 6 speed?

That 3.23 rear gear is deceiving with the 3.2 1st gear. Seems like the overall gearing in each each is much more than a 3.23 with an 833 trans.

That’s a healthy street combo. It should be really tough not to haze the rear tires in an autocross course. You want smooth application of power. Violent action equals violent reaction

So I’d rather trade off low rpm torque.

If you want, clean up the M1 by welding the spread bore up and make it a square bore. Then clean up the inside. Fixed my M1 / Strip Dominator

I think the M1 with it’s more curved runners, is a little bit of a compromise from RPM to Victor. But others with more knowledge on this, might have other opinions.

It’s sounds like a great combo as is.
