Is it possible for the head to get a blockage in the water jacket? I have the factory Volvo manual and I noticed it has some strange "distribution pipe" in the head, can this get blocked????

Yes. you cut right to the chase, this subject happened to be my fist post as well, on my '66 but I had to do the whole runaround.

I had unidentifiable gunk trapped in there, seemed that the more I flushed the system, the faster the temp climbed. I guess it's a kind of bottleneck. Rod it out with something flexible, whatever it is isn't likely to be very solid.

While I was fooling around I installed a thermostat from a Jaguar XKE I think it was. About 10deg C cooler, so fully warm was around 160-165F IIRC. I was paranoid in hot hot Northern California. That car's apart right now, if it's of interest (and that 'stat is still in there) I could check.

Cheers,
-Sean
