Well, my M42 is cooked.
Head is cracked in two places. Cyl #2.

#3

Cylinder 2 is scarred up the worst.

Then I found this. WTF!!! Can you count to ten?

It overheated while driving cross-country last summer. The throttle plate heater hose came loose and a heater core hose ruptured. One hellish night of working on the car in the middle of nowhere. Couldn't afford a tow. But it made it home. Now comes the fun part.
I'm looking for a head if anyone has one they would like to sell.
