Gary,

Since I am a TR6 NEWBE (FNG for all you military types) I dont know if this 
applies to the 6, but on the 3 and 4 engines the manual says to re-torque the 
head after break in. Also re torque the rockers and then check the valves. 
Maybe it is the same for the 6?

Just a guess but any knowledge you cull from this query will be used on my 6 
engine rebuild which is currently in progress.

Bob
