Measure your head or ask the guy that did them what size they are before you but the TB. If you had bigger valves put in most likely they opened up the ports as well. You'll then be able to order the TB with a manifold that matches the heads.

Guy who did the heads says he usually doesn’t change intake. Also the stock TB is still on my bike so I assume it is 1.66” so im ordering the HPI 55mm TB with 1.66” intake
1.9 & 1.6 are the valve sizes.
!.66 will work but I think it's on the small size for a 110. I'd go with at least a 1.710. Since this is a torque build you won't miss the power on top.

Ok but I thought the intake diameter for TB was to the heads and if there is stock on there now wouldnt 1.710 be to big to fit to my heads?
