Re: [Fot] . Head intake / exhaust port question

[Hugh Barber <tr6nut@verizon.net>]

I don't know the exact "average" for a TR motor, but the average EGT for 
a 4-stroke motor is well above 250 degrees. In fact, I think it's closer 
to 1000 degrees (maybe a bit more). In any case, way too high for epoxy.

  I have posted to a couple of TR related sites and have received 
conflicting info to this inquiry: In one of Kas Kastner's recent books 
he shows a couple of cross sections thru the intake and exhaust ports. 
On the exhaust he shows a weld build up location behind the valve guide 
that then gets ground down to smooth the transition of the outgoing gas. 
Wondering if anyone has tried to use MOROSO A + B Epoxy in place of the 
weld and if so what has been the result? ....
