Seems like there's a fair bit of debate on this. Currently putting an Accel base on my engine, and I didn't know about the weird block off plate on the intake gasket before I bought it. From what I understand I should be fine if I delete the T connection to the heater core hose and properly burp the system.
I have aftermarket aluminum heads on here, and I imagine the engine will make more heat because of the cam, too. Mild 355 with 219/225 and superram, long tubes, EGR delete, ect. I also plan on getting a higher flowing water pump since this car will be in a warm climate (Florida). I'd still like opinions on this before I put the intake on, though.

i remember the rear manifold cross-over thing. on my 90 corvette, i had to pull the intake because of a china-wall leak and as i recall, i left the rear crossover passage wide open and retained the "tee" connection. no problems or issues. GM engineers wanted to slow the flow for some reason - probably for some sort of emissions thing. as i remember it was about a 50-50 here on the forum whether to restrict the flow or not. heat wise and performance, i'm thinking it didn't matter one way or another. as for the water pump, installed a premium Flowkooler in my 85 - 8-years now, again, no issues or problems.
