Re: [ihc] header gaskets

[Colin M Rush <salmineo@xxxxxxxx>]

One thing that works is to coat both sides of the gasket with Fe-Pro
Copper high-temperature silicone sealer before assembling the gaskets and
the headers to the motor.  Take the header, hammer it straight if it is
not, hold it against a belt sander to smooth the surface, then coat the
surface of the gasket with sealer, and bolt everything in place, making
sure you tighten evenly.  I used to think it was a crock, but the sealer
does not burn or harden.  It fills in all cracks, seals, and stays
pliable even after heating.  It will seal any cracks you may have,
barring any major gaps, which should be gone anyway after straightening
and sanding.
Also, I am going to be working with a fellow locally who will make
stainless steel/asbestos (or whatever the current asbestos substitute is)
gaskets to fit IHC V8 & I4, and the BG inline engines.  He has been
working on reusable aramid valve cover gaskets for me, and is supposed to
have those in his shop anytime now.  If anyone is interested in the SS
gaskets, or the valve cover gaskets, let me know.
