Great pictures and info Jason! I'm going to try some stock 5.7 exhaust manifolds and see if they will fit in there to break in the cam. I'm afraid the 1st run may be too hot and cook the coating on the headers. Currently looking for some kind of temporary flex pipe I can jury rig onto those manifolds for a startup run.
I have a stock manual steering box and torsion bars. Looks like fun times ahead!
