the 2630 with a 5 fin header would be killer. but it depends on what your track is like
if it is small and twisty with a shortish straights i would say the 2630 with the 5 fin header
but if its long and flowing with long straights i would say the 2630 with a 7 fin header

You got it the wrong way around mate, 5 fine header is more top end

Are you sure there is not any shim in there? Typically there is a .3mm shim for 16%, it is silver. Maybe it is stuck to the button. For 20% add a .1 and for 25% and 30% add .2
16% = .3mm
20% = .4mm
25-30% = .5mm
With 16% I use a 6f plug. with 25 and 30 I use a 7f plug. I am at sea level with high humidity.
Hope this helps.

DJ,
Are these shims in addition to the stock shims that came with the engine or total shims?

The .3 should be in the motor already. The .1 and .2 are in addition.
As for the color of the shims. The .3 is silver, the others are brass.

Then put it in the car. Use a soft clutch that engages very easy and set the 2speed to shift easy also. Run it in the car for about 5 tanks very rich, it may not even shift at first. Key note; make sure to let the motor sit between tanks at all times and make sure the piston is NOT at the top of the sleeve. This methods helps cycle heat into the motor and helps set the piston and sleeve. After these 5 tanks start leaning the motor a little at a time per tank. Over the next 3 tanks it should get close to a rich race tune.
At this point take the clutch off the motor and rebuild it to normal race conditions and reset the 2speed to normal also. Now the motor is ready to race and should run good and consistent.
Hope this helps,
