Given differences, a thicker flange is better. With regard to the collection chamber, I'm sure it makes a difference but on an F/2F we are not impressed with shaving fractions of seconds on out quarter mile times.

I do believe that it is very important to have a header coated. I did a bunch of research when putting headers into the Bronco on the various methods to protect the headers and keep temps down in the engine compartment and settled on ceramic coating. I have a header that I will be putting in with the 1F oiling system upgrade and it will get ceramic coated. I'll likely use the same shop that coated the Bronco headers. For a $200 bucks, it seems expensive but to know it will last a long time worth the added expense.

Speak for yourself!

Just kidding, I am going to go a bit cheaper than the full on ceramic coating. I have a hard time speding that coin there on that kind of upgrade... maybe I am in error, but Marco's recommendation will probably get my coin first.

I know it can really help underhood temps but I am fine with a 3rd world overheatin' beater

VHT is pretty decent, but this quote is misleading:
Quote:
...the same kind of protection that NASA relies on to protect key components of the Space Shuttle.
or... the same kind of protection your coffee cup enjoys in the dishwasher. Sure the same *kind*, but NOT the same THING. Not even nearly.

The proper ceramic coating has made huge differences on Buell motorcycles, and will protect the interior of your header from heat-related erosion and thinning as well as retaining heat instead of radiating it into your engine bay.

And it only has to save your header lifespan once to pay for itself. VHT is nothing like that (DAMHIK, I have a crossover that erodes into steel swiss cheese). It will be replaced with a modified Toyota stainless unit, ceramic coated inside (which has stopped erosion on similar conversions).

Well, it is summit racing trying to sell stuff to the backyard redneck wrencher. Of course it isn't what they put on the space shuttle.

I mean really?

Anyways, it is OK stuff, it is not like a 200 dollar ceramic coating done at a nice shop, but for cheap headers (and we are in the cheap header realm here) the stuff's Ok. Yeah in a year it'll be kinda rusty, and you'll think "wow, I didn't think spray paint would make it that long.." but it'll work fine.

or you can go spend 200 bucks and have somethign really nice.... which may not be a bad idea.

I bought the 1 piece header from JT Outfitters after doing a lot of research on the various types of headers.

What I liked about the JTO unit is the flange is the same thickness as the intake flanges. You dont have to mess with shimming or having anything milled. I used a stock exhaust gasket and copper coat spray. It has worked perfect ever since.

How long ago did you get your headers? Did you take into account the milled out section for the washers on the intake manifold? If so, I am stoked you've done my homework for me!

I thought I would resurrect this thread. I am still undecided if I want to drop the coin on a "professional" coating verses a spray can.

I don't want to be back here in a few years, but a couple hundred bucks could nearly fund my entire "to-do" list right now as well.

I think the last stuff I sprayed on my headers (like 7 years ago at a tear down) lasted long enough for me to set the timing I hadn't heard of the VHT stuff. Does it require baking to work effectively?
