13B engine on dellorto DHLA48, adjustments ?

Hi guys, next week it's the time to swap my SE engine, i'll have all the parts needed in my hand so, it's time to do the job. I have a dellorto carb + RB upper intake manifold, and i'll use the stock lower intake from the gsl-se. I bought a fuel injecter block-off plate, + 13B header, i have all the gaskets for header, and the intake. I bought NGK spark plugs, new radiator hoses because mine were leaking. So, my question is, what are the adjustments that i have to make on my carb? I know i have the change the jetting.. My mods are in my signature. I know a guy who works on carbs, i thought of going to see him and he would be able to tune it properly.

I want to tune it correctly to have the highest power i can get with the 13B. Also, i'm running without actuators, 6 ports opened.

Thanks in advance, hope to find good answers.

Ok, i've searched a little bit, and i've come to these numbers... I found that the only difference in jetting from my stockport 12a is the the accelerator pump jet and the emulsion tube.

so..
12a the accelerator pump is at 90, i have to set it at 80.
and emulsion tube 12a is 7850.4 and 13B is 7850.8

am i right ??
