[Fot] Best Head Gasket

[Jack Wheeler]

 The liner protrusion spec I mentioned in my previous email (.003" - .005") is right from the TR-4 Factory Workshop Manual.  Obviously, this implies use of a stock factory head gasket.  I used this same spec with the factory steel shim gaskets for 24 years in my race engines and never had a failure.  If manufacturers of other head gaskets recommend a different protrusion spec, obviously go with their recommendation.

 Lots of information being tossed around here, I feel this comment is 
missing...

The good folks that have chimed in here have solved their issue of 
getting the wet liner TR motor head gasket to seal. There are many 
solutions that work, but the important thing to realize is there are 
variables to each solution. It's like each head gasket has it's own 
recipe for success. Choose a head gasket and follow the recipe to the 
letter and your head should seal just fine. Some recipe's are easy, 
others require much more diligence. The crux of the issue is setting the 
liner protrusion to the right height for the gasket being used.

Composite head gaskets will hide a multitude of sins when it comes to 
liner protrusion, but may be hard to find a quality one that matches 
your head, plus in theory they may not last as long and may not be as 
robust.

Solid head gaskets require very tight tolerances on liner protrusion, 
are more sensitive to techniques with sealant, and in my experience can 
be a real pain to get the head off! (Thanks Bill!!!) But when used 
correctly should be more bombproof than composite head gaskets, and you 
can order the exact thickness you desire to meet compression ratio 
requirements.

Bottom line to any new guy... Do not fall into the trap of asking 10 
people what they do, then pick and choose steps from different 
solutions. If you find someone who builds reliable engines, and copy 
their solution to the letter, you stand a good chance of copying their 
results.

Worked for me, just sayin'...
