Some folks donâ??t use anything, just real clean.  Personally, I used a thin 
coat of Permatex Aviation gasket seal...after getting it real clean.  Anything 
you put down there adds to the protrusion above the deck for the sleeves.

Folks
Looking for some background information and recommendations on the preferred 
Fo8 gasket sealing compound that seems to have worked for each of you in your 
various engine re-builds.  And  any comments / observations you choose to share 
either on or off list. The motor I am building has a 89 mm piston and liner kit 
from BFE along with Corrello rods / bolts and a Crower dummy main crank 
connected at the front with a ATI Super Damper and at the rear to a Fidanza 
Alloy Flywheel with diaphragm clutch, an HVDA conversion with alloy drive shaft 
to a Quaife 4.11:1 diff. and alloy back cover.  Stainless Steel valves with 
0.050 oversize intake thru Mang. Bronze guides. H/S roller rockers on alloy 
pedestals.  BPNW 270 duration cam. The TR4A head has had 0.040 removed mostly 
to true things up and remove prior imperfections.  The head chambers have been 
mildly worked to smooth any sharp edges and even things out with a resulting 
chamber volume of 60.5cc each.  I am planning on installing Gasket Works 0.022 
copper gasket with their 0.005 â??Oâ?? compression rings on the head side of 
the gasket that will be sprayed with a copper coating on each side.  Gasket 
Works sent a set of Fo8 individual gaskets that has allowed me to obtain a 
liner protrusion of 0.0025 to 0.003.  Am aiming at a compression ratio of 
around 9.75 to 1+/- . Looking forward to as many responses as possible to 
assist in trying to get this critical step as close to right as I can.
