[Fot] Stock Head Gasket - Sealant?

[Jack Wheeler]

It has been many years since I installed a stock head gasket on a TR-3/TR-4 engine.  I'm helping a friend with his TR engine.  It is a stock rebuild and we are using a stock head gasket.  Does anyone have any recent experience with stock head gasket sealants?  Should we use a sealant, or install it dry?  If using a sealant, which one would you recommend?
While I am at it, let me also ask about rear crank seals.  I understand there are some new ones available since my race car days.  I'd be interested in any recommendations you might have.  Use a new stock rear seal?  Or, is there a better option now?
Thanks for your recommendations.
