Default Intake manifold options

Hey folks, working on my 80 Camaro that has 89 Corvette L98 heads. Looking for an intake manifold setup for a carb that will fit these late model 350 heads. I tried looking on summit and jegs, and couldn't find it. I know they're out there, I saw them a few years ago, just don't remember who makes 'em. Any help is appreciated, thanks!

How about the manifold used on the ZZ4 crate engine based off the L98 heads?

Vette alum L98 heads have the same bolt angle as all the early SBC engine ; don't have the canted center bolt holes like on the '87+F-bodies ( cast heads )
so any SBC manifold should fit.

The determing factor is the HEIGHT with carb in regards to hood clearance.

If you look at most manufacters listings for '55-'86 intakes they state :
"Not for 1987 and later cast iron heads. Will fit 1987 and later stock aluminum head"
Not LT1 obviously.
