Ya mine slightly rubs the steering shaft as well, but I didn't bother making any adjustments to the headers themselves...should be ok i think...

IMHO, get coated, the black painted ones i think would look terrible in a couple years

 

More like a couple of days or weeks.

 

Yes they will!! But what does it really matter? You can only see a little of them and i dont drive it in the rain or snow so they should look all right up top and it saved me $200.00 now!!! For other parts.

 

It will matter when they rust through and you have a huge exhaust leak.

 

I keep the car garaged 99.999% of the time so i was thinking of having some dry the air crystals to keep moisture out of the air. This should help a lot.

 

Mine is also in the garage if im not driving it. They should last a looong time!!

 

Concrete is permeable. The moisture can come right up from the ground below it and start to rust your car and headers. Thats why sometimes you'll see low mileage nice garage/barn find old muscle cars and the underside will be covered in surface rust. When I got my LT headers for my Mach 1 back from Jet-Hot it had something about how if you store your car on a concrete floor I think you were supposed to put a tarp down or something under the car to prevent the moisture from coming up. I'd just coat the headers, if not they'll look like total garbage in a few days.

 

Not only that but concrete never fully cures. It always has some degree of moisture content. I really would like to seal my garage with that stuff you always see in the magazines.

I don't have a concrete floor! It's wood with insulation under it and carpet on the floor so no moisture! It's just like keeping it in the house(LOL) It's an old garage that the first owner built just for keeping his OLD car in.
The headers are painted(I did it) with gray hight temp. paint thought.
