Those center ones are EGR passages. Since Corvette does not use them, we don't need them. :) The F-Bodies use an internal EGR passage from the heads to the intake manifold as opposed to our external one.
p.s.
I run those exact gaskets installed as is, they work great. I've got a set sitting on the floor waiting to go on when I get the heads back. Just install them with the "this side up" up. :)

Re: L98 Intake Gaskets (chucks88)
My stock intake gaskets looked like yours, with the rear coolant port blocked off except for a small steam relief holes.
My replacement gaskets were FelPro #93317 & #93318 from the MS 93318 gasket set. These also had the rear block-offs with the steam holes.
I think the open coolant holes are intended for earlier Vette L98 or F-body L98, but I'm not sure if it realy matters.

I used the same ones. They matched up with all the ports in my heads, I guess these iron blocks have more holes in em. I believe those two end ports are dead-ends in the cast iron heads, so coolant and crap just settled and corroded in there... which was why I had to change em.

From what I'd seen today..it looks damn good! And Chuck's pretty much tackling it Himself :cheers:
Chuck, let me know if you need any other assembled SR photos. I have some of the old way also.
With the accel base; clearance on my old distributor wasn't necessary. Must be required on the edelbrock?

No problem. Had a good few laughs.
Yes, went to NY. Good to go. No traffic for once, I'm going to re-do my sig pic with the DFI display screen. It's neat!
Let me know how the rest goes.
