Are there any thermal coatings we can do our selves?
I was just looking for some thing that could go on the rough exhaust ports of my cast iron heads I ported.
Ether coat them or just let carbon build up on them to insulate them.
Is there any kind of home thermal coating spary we can buy and do at home?
These are turbo heads.

There are several I do believe. Check www.swaintech.com I thought they sold one you could do at home with an oven, etc for small parts.

This would be the best place to buy from. They have been sell these kits for years... http://www.eastwoodcompany.com/jump....ORY&itemID=460

I haven't worked with the coatings, but I would like to point out that carbon is not a good insulator. It is a electrical semiconductor, used to make cheap sparkplug wires and most resistors. Anything that tends to conduct electricity will conduct heat as well. Has to do with physics, and the free electrons.

Coating might do some good, carbon will not be as good as coatings and only a little better than bare metal.

You can't avoid carbon build up, but it won't help you very much.

Nice powder coating kits but not what he's looking for, nor is THIS.

The swain link above is the "stuff"

I've used the techline coating a couple times. We never did before and after tests, but it was still intact when the engines were disassembled.
