12g940 head on a 1098 standard engine.

Hi, I'm just corroborating what I told a fellow MMOC member. That is: A 12g940 head with the exhaust valves properly recessed is a good improvement on a standard 1098.
Opinion welcome - also would anyone recommend a needle change on a standard carb for this change.
Many thanks
