Edelbrock Intake Issue

I haven’t laid eyes on a Performer intake in a very long time. I have no use for such an intake. I don’t know if those “Other” thermostat holes go through or not and if it’s not for the majority of intakes, it’s an auto check the second it comes OOTB.

I have never —- at least I don’t think so…. Used a “O” ring housing. The stock iron housings have not yet failed me.
