First of all, I would like to say thank you for this great write up. It has been helping me greatly as I am doing the head gasket change (i'm not done yet).

I would like to make some suggestions for what I hope would be an improvement to this write up.

First one is the picture of how you need to pull the pin on the guide rail.
I was able to find one after seaching the forum, but it will be better if it is already on this post. Here is the link to the post that covers it.
72 250c head removal help needed.



Basically what you have to do is after installing the longer screw with washers, socket into the pin, hold the longer screw with a rachet from spinning and turn the nut clockwise. The screw I used was 6mm diameter, 1mm pitch and 50mm long

The second recommendation is on the triple square (XZN) bit.
DO NOT GET IT FROM AUTOZONE OR EBAY!!
Maybe it was my fault but after I was done loosening the head bolts, this is what happened to it.

Instead get SK or SnapOn.


perhaps I should have checked and see how the bit was holding up after each use. I'm going to have to clean up all the metal pieces in the head tomorrow from the autozone crap. thanks Autozone!!
