After a failed experiment with some decompression headgaskets(namely combustion gasses in the coolant), I've learned that the IDI platform does /not/ like decompression. From hard starts even when mostly warm, to smoking badly when cold, it worked... but not very well.
So, back to stock gaskets. It took me all of 2.5 days to pull the engine, replace the gaskets and reinstall it. A pain, but I'm getting good at it.
So, here she runs. I was a little worried about it, after what I saw with the heads off:
1. vertical scoring on multiple cylinders(like .015" wide scores going up the cylinder wall, 3 or so per cylinder), though all the other surface looked mint. I guess I must have gotten some hard crud in there at one point... sigh
2. Head cracks between the intake and exhaust valves on cyls #2 and #4. Doesn't seem to extend down onto the seat, but still a big crack. And this was the head that had been rebuilt and fixed when I built the engine.
The passenger's side head was just one from my junkyard, had gotten water in the motor for a while and had some pitting on the bottom side(In the combustion areas only)... but it works just fine.
Well, that's the IDI for you: Impossible to kill.
