yes you are right, the tbi gaskets(felpro ms93317) only have a small hole at the end , they are not fully open, this is so the engine gets to ideal temp (94 degrees).
if the open type felpro 90314-1(carb) are put on a tbi engine it will never get hot enough and run rich, there is a temp sensor at front top of block, this tells the tbi to lean up the mix when 94 degrees, if the engine dosnt get this hot it will effect the whole system , map sensor, egr valve, o2 sensor etc etc...it will foul the plugs very quickly
i can tell you this from 1st hand experience.
im no expert but it makes sense the opposite is probably true and tbi gaskets on a carb engine would cause overheating.

|skersfan||Ok im a staight rookie at doing this stuff this car just been sitting around so im just using my spare time to fix it but on ur pic there wat are the 2 round gaskets used for ?|

If your heater circuit comes off the front of the intake where the return collector is, then a gasket that blocks the rear returns would not be a problem.

|skersfan||Ok thats the exact set that i have the reason im asking is because the set out of my car has one of the back ports open and one closed but ill put the new set in n see wat happens thanks|

i pulled the gaskets from my 89 caprice classic and only one of the ports on the back of the old gaskets were closed and my new gaskets both of the back ports are closed will this still work or do i have to go buy new gaskets again

This isn't necessary on most street-bound engines.

On my 350, a previous owner had run a hose from the back of the manifold to the opposite cylinder head - I wondered what that was about. I guess it was someone trying to put a waterway where there isnt one, for what purpose Im unsure.
My Weiand inlet manifold has no waterways in the rear of it- so I presume it isnt important to running temperature.

There is no passage in the rear of the intake, as I mentioned before. The front passage is what is used. The gasket is similar to the heads- one gasket (like one head) will fit EITHER side of the engine.

|hemi joe||ok than what is that rear passage for.i don't understand,i need to be educated.|

The "traditional" intake gaskets have holes front and rear- this is only so one gasket needed- one gasket will fit both sides of the engine.

|hemi joe||not true,the gasket for my car has the rear ports open.gaskets for tbi are closed.look it up,i have a 5.7L/350 CARBURETED MOTOR.TBI IS DIFFERENT GASKET.LOOK IT UP!!!the 87 roller motor is different,believe me,you guys are being stuburn.get off your high horse and look into this!!!|

The SBC intake gaskets have water holes in both ends so that they are interchangeable and can be used on either side of the engine. There are no rear water ports in stock OEM intakes, it is only aftermarket performance intakes that have water ports in the rear, for the guys who want to modify their engines for four corner water return.
It would have nothing to do with your overheating problem.
