Correct Intake Manifold Gaskets for L98?

[jgmotto]

Does anyone out there know the correct part number for an intake manifold gasket for an 89 L98 with stock aluminum heads? The parts store listings show a lot of different ones. Some have the rear port blocked off. Some have the center port baffled with metal. All different port sizes. I have a set of 1256 Fel-Pro and a set of 90314 Fel-Pro. Are either one correct?

You should be able to compare the old gasket to the new and return the one not needed.

Correct gasket has a metal plate with a small (1/16"?) hole on rear coolant port.
Center (EGR ) port style is irrelevant as alum L98 has no EGR passage there in either head or intake

I installed Fel-Pro 93318 on my 1989. Picked them up from NAPA. They have a small hole on the rear coolant passage that matched the set that I removed. Here is a link to Summit Racing.
Fel-Pro QMS93318 - Fel-Pro Intake Manifold Gaskets - Application - SummitRacing.com The set did not include any front or rear manifold gaskets. They supply a tube of black RTV sealent.
