Tongue Install



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.'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.
