Anyone ever tried? I'm thinking of building something pretty crazy and trying to do my research now...

SBC headers will not fit a LS1 no matter how you turn them

If you mean shorty LS1 headers on a LS1, sure, they can be oriented any direction much like a you can on a SBC. Engine bay clearance is a premium and without knowing the brand of shorty, or recalling anyone doing a turbo LS1 with inverted shortys. It becomes difficult to answer

that's the idea. I want to build a twin turbo car using flipped shorties, though not sure if they will point up or down.
