RE: Headers

["Theo Smit" <theo.smit@dynastream.com>]

At the last SUNI, Doug Jennings Sr. had some pointed comments about Allen
head bolts on headers... My header bolts came undone without too much hassle
when I took the engine out, although I could see from burn marks on the
gaskets that I'd had a few leaks at the exhaust ports (which it always
sounded like... I just never knew for sure where the leak was). 

I'm no expert on fastener and threadlocker technology, but I wouldn't use a
threadlocker on exhaust bolts - I'd just use antiseize. The blue medium-duty
threadlockers soften with heat, and the red heavy-duty stuff would probably
be a little scary for bolts that you need to remove with only a limited
amount of tool room. The possibility of tearing the threads out of the
aluminum heads isn't appealing either.
