Thanks for the great advice .. I will try to follow it .. not sure how 
accurately I can check the measurements.

I don't have flat washers .. I only have lock washers.  Do you think the 
"Moss" hardware is better than going to a fastener outfit .. what grade 
would I specify?

I found reference to "smooth face downwards" under heading 17 re the 
"Low compression kit" ..page 27 of "Service Instruction Manual"  but 
couldn't find it elsewhere in that book.  So i went out and found 
Kenneth Ball's "Triumph TR2, TR3, and TR3A 1952-62" Workshop manual and 
it also said on Page 13 "a new gasket smooth side down".

Based on simple principles, there are different surfaces on the block 
side (4 sleeves, block) and only the head up top, so without knowing 
anything else, I would conclude that smooth side to many surfaces and 
non-smooth to the single surface ....  ie  Smooth Side down.  But that 
may be too simple.
