[Healeys] Valve guides

[David Nock]

As Michael states in his blog there are many problems with bronze  
valve guides causing problems with sticking valves on acceleration.
What we do is leave the cast guides and install a very thin bronze  
insert into the original guide. This get the advantage of both the  
cast iron and the bronze guides.
