Unfortunately I already had it all together when I saw this. That said the O-rings were shot. They were all hard and brittle. I replaced them with the springs. Primed the motor with break-in oil, ran it for 5 minutes at 2,000 RPM's, and now I need to re-adjust the lifters, change the oil to new, proper oil, and re-adjust timing, etc.

The important thing is she runs! Haven't driven it yet so I don't know what kind of difference she'll have over what it was before. Hopefully that'll happen tonight or tomorrow night.
