Head plugs

["john price" <jprice1@txcyber.com>]

In most TR-6 racecars there is a head plug where the EGR valve came out. 
Many of these have been re-tapped for a 3/4" pipe plug. If anyone cares, 
the stock thread is a 3/4" JIC thread. There is another plug in the block 
just above the oil filter attach point. Same thread - same size. Re-tapping 
these is no big deal, as long as you do it before you assemble the engine. 
I didn't. So I used 3/4" JIC plugs liberally doped with red Locktite. Stay 
tuned - so far they aren't leaking.
