Bud, Scott,
Chilton's tune up and repair guide for the TR (everything) says to tighten the
screws from the center out. John Norman, an old Army buddy (senility
setting in) who's father owned the Chevy dealership in Tyler, TX, helped me
rebuild a 283 for the 64 Chevy van I had back then. One thing I still
remember is him telling me to tighten anything with a gasket from the center
out, oil pan gaskets, etc. One of the few things that even massive quantities
of beer have failed to erase.
