teflon gasket jointing material...
it is the engineers choice of material for high temperatures and high pressures... non reactive, doesnt stick, easily dismantled, squishes to minute clearances...
from memory...300C+ at about 4000psi.
your (worked, high compression, high performance racing) engine will be lucky to get a peak pressure of 1000psi
there is a "special" teflon string available, but as mentioned..teflon tape, twisted into a string works fine. and is a lot cheaper.
if you want pink or yellow, go for it, ive always just had white stuff on hand. its still teflon.
it may take a few goes to get the technique down pat. dont worry about popping the head off again to make sure, practice makes perfect!
they (?) also recommend very minute grooves cut into the sealing surfaces...a dead smooth, flat surface has no "grip" so to speak. think of an LP record sorta thing. as the head comes stock, is fine. unless there are any obvious gouges in it...leave it alone.
