an idea from last night...
1. sheetmetal lifter valley cover. i would cut a piece of sheetmetal the same size as the bottom of or stock manifolds to cover the valley, and use RTV to seal the ends.
2. as the LS1/6 etc intakes have individually spaced ports, that would pose a problem to the old SBC style 1 2 1. but i had though of moving the middle ones 1 step closer together. as pictured below. also using the LS intake gaskets. i used the LS6 intake since it looks cleaner lol

- dont mind the 10 min of photoshop lol
the only thing i could think of that would be a little wiery of extendint thoes 4 runners would be the A/FR for cylinders 3,5,4, and 6.
again, i wasnt very serious about this, it was just a little creativity.
