Ok, what's next. I put the stock truck exhaust manifolds on and there was definitely a spatial conflict between them and the frame rails.

The drivers side is worse but nothing a little surgery couldn't cure. I also had to make a relief for the steering shaft, it protrudes about a 1/4" into the exhaust path. The drivers side will still flow better than the stock stock passenger side tho so I'm content with the way it turned out. I have no idea whether they'll hold up after a few heat cycles but they are currently crack free. I'll get some pics with them mounted as soon as the engine is back in.
