Intake headers LS 6.0 to sm 465 1970 gmc

[weedoublewide]

Good evening everyone,

I've run into a clearance problem involving my exhaust headers with bolting an LS 6.0 to an SM 465 transmission. I was wondering if anyone has encountered this problem or knows of some block hugger type manifolds that they've used in the past on prior projects.

The Gen 1 exhaust manifolds, like the ones from the sbc 350, would be perfect as they're a tight fit to the block. I found a pair of Hedman 68520 but they protrude out 4.5 inches out past the frame.

I also tried a pair of Hedman 45660 headers but was informed after I tried installing them were for hydraulic clutches setups, not manual clutches.

Any and all advice is greatly appreciated,

Thank you and Merry Christmas,

double
