[Mg-mmm] PA Engine question

[Lawrie Alexander]

Folks,

First - the good news. My first-ever rebuild of a PA engine seems to have 
gone well! It started up nicely, has no leaks (so far!) and a short drive 
suggests it is definitely more powerful than it was before the core plug 
incident which necessitated a tear-down after just 118 miles on the 
"specialist's" rebuild.

Now I have a few questions: Does the head need to be re-torqued (this is my 
first experience of building an engine with a solid copper head gasket)? If 
so, re-torque when hot or cold? Should the rocker arm clearances be set when 
the engine is hot or cold? My experience with conventional engines says 
"yes" and "hot" to both but I am trying to do this engine once and 
correctly! Lastly, I have seen recommendations for rocker clearances at 6 & 
6, 6 & 8 and 8 & 8 thou. What is best? (This engine has a Centric blower.)

Advice from those of you with lots of ohc experience will be much 
appreciated.

TIA,

Lawrie
