For anyone who might be interested, I just finished putting back together the two cylinder heads that needed some repairs. In the end I decided that since this car is not worth much, not much money will be spent on it, so the old valve guides were reused. All were within specs. I made a tool to readjust them all to their correct height, and although they will drop again, by that time I hope I won't be needing this car anymore, it's just a winter beater and a back up car so I can do so quality work on my benzo. The heads were resurfaced, degreased, adjusted, valve seals were replaced, leak down test shows that they still hold very well. Tomorrow I will start putting the car back together, hopefully it will run when I'm finished with it
wish me luck.
