Right?

Great opportunity to dispel any myths and supply genuine data in regards to this modification.

The ONLY work performed on intake #1 will be the 3 angle, and simple blending of the new seat into the bowl(less then 3/4" deep)....



... looking at the splitter that is evident.


The other 3 will get ported.


This view shows that the oversized seats in chambers #1 and #2 have been blended, but careful viewing inside chamber 1 shows the blending is only so deep, and that the guides are still untouched





A different view, this time at the mostly finished #2, and the yet to be started #3




More to come........
