A = original
B = slip fit version designed to reduce production time and cost, while A style headers were being finished.
B headers are nearly identical in performance, but are not as smooth as the A internally, and are being phased out.
150/250/350 = merge collector type. 350 has the fattest overall powerband, and has proven to also be the most popular.
A/350 is what CSG originally tested.
The CS/400 is a B style construction with even more low end power.
We have an A/400 final prototype that is currently at the ceramic coater, which will be validated, and then that will also be production ready...
TL;DR: buy the A/350.
