[Mgs] bronze valve guides

[WSpohn4 at aol.com]

Didn't the same shop finish the guides to the valves you are using?   If so 
you should be OK - but they need to have been finish-reamed to exact  size.  
Call them up and ask them (and why are you puling the valves out  anyway?)
 
If they installed them without the valves, take the head back, Pressing the  
guides into the head deforms them ever so slightly and IMO requires fitting 
them  to the valves used.
 
Normal procedure is to hand the shop the springs, valves, etc. and get back  
an assembled head ready to drop on.....

On my  past engines if I have the head on its side and install the
valves, when I  place the head down, the valves will fall with no help from
me.  With  this head, the valves do not move and I have to push them down by
hand  before they will move.
