Ceramic coated heads

Has anyone ever used silver ceramic coating on your flathead aluminum heads or intakes to keep the funk off? Any pros or cons? I'm pulling the flathead out of my roadster this winter to paint and re-seal. I'm going to ceramic coat the exhaust and have been considering the heads and intake at the same time....Thanks

 

Ceramic coating is a heat barrier, so I know if you'd want to use it on your heads. Why don't you call HPC, Jet Hot or ????? and ask them?

 

I have used it in the combustion chamber areas on several flatheads. I used the coat it yourself type that you heat up after your done. It seams to even out the heat and gives ya a little more power. I like it.--TV

 

Err, yeah, it's a thermal barrier, not good for a part that needs to shed heat. There ARE several thermal emissives on the market, coatings which shed heat better than bare aluminum, paint, etc. We used to use a thermal emitter on oil pans, intake manifolds and brake calipers on our various race efforts, and they worked well (We also used combustion chamber and exhaust port coatings, whick kelped tremendously.) I've been working on a method to coat the exhaust ports in a flathead block, but it's a bit of a pain, given the length and tortured route.

The thermal emissive we used was a brownish grey, so I don't think it'd look very nice on a flattie head. On the plus side though, it was kinda semi glossy, so it was easy to wipe clean.

 

It goes on reeeeaaal thin. If you coat an intake or heads that are rough (sandcast) the roughness shows through. Those types of parts need to be smoothed first. Any part that is polished or smoothed down would probably look nice.

 

I workin on doin the complete drivetrain in a high dollar pickup I'm building and Caps Cerma Chrome said it was fine he has done a quite a few engines with no problem. He does all the thermal coating for the high dollar hot rod guys. He is in Fresno, Ca.

I've had my intake done and it looks good with no cleaning required. It also helps your fuel runners do to smoother surface equals boost in power.

 

I have done the heads of the PISTONS for my flatty.
Then the skirts have been "Dry Lubed."
