Re: [DML] Head assemblies

["Dave Swingle" <dswingle@xxxx>]

Minor problem here. It's kind of difficult to magnaflux an aluminum 
head. It's not magnetic.

Also - you are NOT supposed to grind heads on the PRV, if you do more 
than microscopically the front end plate will no longer fit. (This 
plate covers the whole front(belt end) of the engine, including the 
heads.) If the heads are much shorter than as-designed you'll have a 
problem. 

This is explained in the technical manual as well (I believe, it's 
been a long time since I re-read it!).
