So after getting back and investigating what actually went wrong I found the cams timed to each other correctly, and they were both timed to the crank damper correctly, which was advanced a few degrees in relation to the crankshaft itself.
I am assuming one of two things happened.
1) The crank locking tool that engages the flex plate teeth knocked the crank backwards a few degrees while I was installing it
2) The crank damper moved forward a bit as I torqued the bolt down.
Either would have put the crank off in the direction I found it.
Either is plausible, since all the timing and holding tools except the crank locking tool are removed during torqueing to avoid damage if something moves, per the workshop manual.. I particularly avoid leaving the damper aligning tool on as I have seen the oil pump get broken by trying to turn the engine with it in place.
I reset the crank today and started it. It fired up much faster, but I didn't run it long since I still have a leaking heater hose.
