Tongue Install Notes

Funnelweb port tongue installation notes
 

A good solvent [acetone or lighter fluid] would be good start [assuming the
heads don't have any carbon in them, otherwise you'll have to remove it]
Put tongues in place without epoxy & check for fit, & take note of gaps
where you may need that little extra epoxy. The most important part is the
end of the tongue [near short turn of port] make sure the tongue sits down
neat before using the epoxy. You may have to bend it down very slightly.

It's a good idea to check the face of the tongue to see if it is sticking
out at all, it may need a little finishing. Now put a very thin smear in
the head as well as the tongue ["THIN", you don't want to jack up the
tongue] & press down hard on the short turn end of tongue, otherwise the
epoxy will lift up the end, especially because the tongue is very thin & can
bend up easily. Also keep an eye on the front of the tongue to keep the
floor horizontal. [they have a tendency to twist slightly] Wipe away excess
epoxy & wait for it to set. Then tidy up w/dye grinder. Then drill hole
thru bottom of head/tongue & use a self tapping screw or capscrew, with a
little epoxy on the threads for insurance.

Don't assemble head until you dummy up heads & intake on block using all
gaskets [preferably used gaskets] & check for any port matching that may be
required.

Gaskets...you're stuck w/stock 4V gaskets, you could buy some gasket
material, & cut out the same as the tongue & silicone to the tongue, but I
really don't think it's necessary.

Also recommend removing a reasonable amount of metal off the push rod bump
on the left side of the port, this will pick up flow slightly.
