Re: valve clearances

[Kevin Trent <trentkc@domain.elided>]

I always lean to the tight side for the additional lift, and just set up a 
1750 head on a rebuild project with the lash set at .015 intake and .017 
exhaust.   I have a 2L that is set at .014 and .016.  Perhaps some more 
knowledgeable digester can provide reasons why this is not a good practice 
- the most obvious is the possibility for insufficient piston 
clearance.  It would seem to me that an important consideration is 
uniformity across cylinders, but I don't know how many thousandths would 
make a difference until cylinder "inequality" would affect how the engine runs.
