Interesting.
I’m still a little confused by this because L6 does not have a firing order that shares ports. 1-5-3-6-2-4. So, there is no intake overlap.
I guess I am stuck on the thinking that if the charge is sitting on the valve, it can’t be stolen by the Siamese cylinder.
So, the ultimate solution to keeping cylinders 1 & 6 from going lean, is port dividers (or 12 port head). That will control the charge going to each cylinder?
😒 wishing I’d continued with the dividers.
