===Unknown lash recommendations===
Most cams have an ID engraved or stamped into them, often on the back end of the cam.:( It would be really good to know exactly what cam you have so you could use the right lash settings. Reason for this is tight lash cams have a relatively small window for deviating from the recommended lash settings. 

'''From Crane:'''<br>
{{Warning}}<br>
"Tight Lash" camshafts cannot deviate from the recommended hot lash setting by more than +0.002" ''increase'', or -0.004" ''decrease''. "Tight Lash" cams are those which have recommended valve settings of only 0.010", 0.012", or 0.014" on the specification card. These lobe designs have very short clearance ramps and cannot tolerate any increase in the recommended valve lash. The extra clearance can cause severe damage to valve train components.

With "Tight Lash" cams, we recommend using only the prescribed amount of hot valve lash, and that close inspection of the engine be maintained. Please realize that changing valve lash settings from the recommended design specifications will change the harmonic characteristics of the valve train, possibly causing valve spring deterioration and breakage.  

The following procedure may be used to be sure that the lash doesn't change excessively when hot, and to get a cold lash setting that will give the hot lash that's wanted:

#Set the lash cold cold
# Bring it up to temp
# Measure the exhaust valve lash, then the intake lash. You could do this w/the engine running, or off if you're quick about it.
# Compare the cold vs. hot lash to see what (if any) change there is 
# Use the results to come up w/a cold lash setting
