View attachment 1715412331This is the 4611s I have. Isn't this a spread bore? Also I have this on a OEM 68 340 Cast Iron Intake, Bores match. The plate (adapter) i have is just a heat sync plate, not spread to square.

technically, the bores are spread. It's called and referred to as a square bore, like the edelbrock carbs. '68 340 intake is a square bore - 4 hole.
