Tuning Flathead Twin Carbs

Does anyone have any feedback on tuning Twin carbs for a flathead?
Motor is a stock military 239ci factory relieved block with Fenton exhaust headers and an Eddie Meyer intake with 2 x Stromberg 81s. Air cleaners have K&N filters in 'em. My question is...what size jets should I be running....stock are #35.

 

i would like to hear some numbers, too .

hey guys, on 81's you can go up to 37-39's and get a little more out of them without flooding the engine with fuel.

Dickster is right!!

But I'd switch from 81's to 97's or even 48's if it were me....

what about 94s..

 

94's would work great. Just be sure to read 286merc's directions on 94's in the tech area.
Whos running triple carbs on their flathead??
What size jets are you running on a progressive linkage setup?
