440 ordeal continued

No compression is a result of either terrible ring seal, or the valves are not closing for some reason.

Causes of valves not closing: bent valves, valve bind in guide, rocker arms adjusted too tight and holding the valves open, etc.


-- "zero lash, and 1 turn"
This seems a bit much. In theory the lifters should be able to accomodate, but a full turn is a lot. I am referencing the small block chevy world, where it is quiet plus 1/4 to 1/2 turn. For reference, your adjustment is 1 full turn after tight, and that might be enough to unseat the valves, losing pressure??? Maybe?
