Intake manifold modifications
In Kas's Historical & Tech. Guide for Triumph Cars on page 58 is a cut-a-way of the intake passage in the manifold showing a "weld" area behind the intake valve guide that after shaping softens...

The temperature of the exhaust port gas is going to be in the high 1200-1800 degree F or higher so I don't think there will be much chance of the epoxy holding up. It will be outside of the combustion...

Kas is right about the exhaust port temperatures being too high for epoxy, but you were asking about intake port modifications. Aluminum melts a hair over 1100 degrees and yet they make cylinder heads...

Did some further research, and found out more. One friend and shop owner used to machine the entire exhaust port out on Suzuki drag bikes and reshape them with Belzona. Another engine builder that...

I presume you are still talking about the inlet ports not the exhaust. If it is the exhaust I'd sure like to hear your results.

I'm sorry if I did not make my self clear. Jim Quin of Chassis Service Unlimited, spoke of using it on exhaust ports on Suzuki drag bike. Think 9 seconds max. The other shop I spoke to was Tom Olsen...

I raced Formula Ford for years and we bought our engines. Heads that came from a company on Long Island NY had epoxy in the intake. They were recycled several times over a some years and the epoxy...

The difference is more than you'd suspect. Think a pulsing but constant flow of cool air (plus evaporative cooling from vaporizing the fuel) versus a pulsing but constant flow of super heated exhaust...

I have heard from several people that have used that type epoxy in the inlet port. I have no experience in that mod as we were not allowed to ADD anything per the regulations a the time. I think you...

Everybody using material in the manifolds should be aware of pulsations.I could hear from a friend who found ceramic particles from the cathalytic converterin the oil pan where it moved via combustion...

Epoxy seems to work okay in the inlet ports, but I certainly would not try to use it in the exhaust ports. The exhaust temperature is just way to high for epoxy to live. That has been my experience...
