Thanks guys.Dave I'll check for that part.It would be better than filling them in case I ever want to use the heads on a daily driver.
Mike,these are egr smog heads that allow the engine pistons to blow hot exhaust straight out toward the carburator(into the open air around the carb in this case with the intake notched).This is a race intake and I'm not familiar with the reason for this notch.Maybe it was on a turbocharged motor???
Mike I'm sure with your experience you've seen these,I must not be explaining very well.This intake doesn't have a heat riser,even the part of the intake where the heat riser would bolt to is notched out,,,gone,,,.I presume it is that way for some race application?
