[TR] TR3 Head gasket replacement

[LT]

I am going to do a head gasket replacement in the next week or so.

Read through the archives and found some info from a few persons.

Does anyone have any specific do's or dont's with the actual gasket and 
head installation?

Have taken the front cowl off to repair the radiator (leak around the 
neck) and was wondering if there are any other items I should tackle. 
(Crankshaft timing cover front oil seal)

The car is a 1957 TR3 which had a restore/rebuild around 1985 and has 
about 5000 miles on it since. Sat around for the last 5 years.

I had problems with white smoke exhaust after getting it started (wisp 
of steam in the #1 cylinder when I pulled a plug). No sign of blown 
gasket or antifreeze leak.

Head looks okay.

Any ideas would be appreciated as I don't want to do it a second time.

Thanking all in advance for any input.
