tti's wont fit 6 to sb

im at the point where im buttoning everything up on my slant 6 to 340 swap on my 69 valiant.

I cant get my driver side header to fit it's interfering with the torsion bar and column auto shift linkage and i can not raise it enough to start the exhaust bolts.

Im using mancini engine swap mounts and have tried mounting them to the front and rear of the ears on the engine. There currently mounted to the front but when on the rear of the ears the header hits the power steering box in 3 or 4 places. the engine was located per the tti instructions.

any suggestions.
