Need to make a decision fast 5.7/6.1/340

Yes, I am running the HDK, but that manifolds are still the same ones you want.

The LX manifolds will clear the drivers side, but hit the frame by about an inch on the passengers side so you would need to notch the frame for clearance.

The truck manifolds dump into the firewall

Will those manifolds fit facing forward by swapping sides? Just wondering for a Single or Twin Turbo install.
