Rebuilding an 821 is EMOTIONAL
skippopotamus:
Here's a strange one which has me stumped. When I try to adjust my valves I have to spin the adjusters down so far that the locknut barely has any threads to bite on. I am not using my original head because it was too rough and my machinist felt that the guides would be too loose in their holes. I found a nice, uncut head on Craigslist but it is probably not from a Europa. I am using a Europa cam shaft, tappets, and push rods. The head all torqued down to the initial (before warm up re-torque) spec.
I am hoping someone knows of some longer adjusters I can use. I really, really don't want to remove this head because getting the liners to seal was a bear. Maybe I can have some longer push rods made?
skippopotamus:
I should have Googled before I posted. These guys can make either custom length push rods or adjusters.

Did you have the cam reground?
What is the thickness of the head compared to the spec in the manual?
New valves? Different installed length?
skippopotamus:
Hi John, I did have the cam reground. The hardness had come off of it.
We did measure the head and it is within spec. It hadn't been cut before this and we just took off enough to make it flat.
The valves ended up being ok so I reused them.
jbcollier:
Did you reuse the valves from the old head, or the new?
