67 C10 V8 Correct Exhaust Manifolds

[J&J67C10]

Hello all, simple question, I hope. What would the correct ram horn exhaust manifolds be for a 1967 C10 with a 327 be? Straight drop or angle drop? When we bought our 67 it had a transplanted 350 in it with a straight drop manifold on the passenger side and an angle drop on the drivers side. I am in the process of installing a new exhaust system and I would like to put the correct drop manifolds on as part of the job. Thanks, JandJ.
