The only thing I can think of is a beam type torque wrench. A clicker type
will not give accurate readings due to the length and flex of the head
bolts. It is a must have. Otherwise, micrometers and calipers and balances
for measures as for any motor proofing are needed. Setting the ring seals
can be done with thumbs in some cases and pipe arbors made up at home,
however, considerable skill/patience is required least you foul up the new
seals.
