Correct TPI Intake Manifold Gaskets?
I have searched and read till I'm blue in the face and I cannot determine what intake manifold gaskets are correct for 1989 TPI 5.0. Want to use Fel-Pro and purchased a 1204 set, but they have the center port blocked. Can anyone out there please tell me the correct Fel-Pro gaskets part number? Don't need the plenum gaskets; already have those. Just need the intake gaskets. Thanks.

Thanks. For some reason, Amazon says not for my vehicle. They look correct, just needed some verification.

They are a standard older sbc gasket. I think I have used them in the past. It’s been so long I’m guessing here.

You could always get the locally and return them if they don’t match up.

It shows to fit 85-86 camaro with a 305 base model I would guess carb
it doesn’t specify. I’m sure I have used older sbc gaskets for tpi.

this fits 85-92 tpi so I would assume the base gaskets are the same.

the 1204 should have a removable piece for the egr passage center port.
the port size would be larger the only advantage would be if you port the intake and heads.
