Assuming you run a TBI block with the bypass holes drilled out in the Vortec heads (probably irrelevant, but including it), what intake gasket set should be used? There seems to be a lot of debate on the importance of running TBI intake gaskets, something to do with the way the coolant flows for the OEM TBI intake's plenum. OP mentioned running regular gaskets and letting coolant flow where it wants, but I want to revist that point. I'm hoping to get my hands on a good used GMPP Vortec TBI intake, but if that deal falls through I'll probably go the carb/adapter route. I'm not sure how the importance of that TBI blockoff translates when using other intakes. Since the Vortec heads have such a different intake lip height, would TBI gaskets even work on Vortec heads?
