any tips on putting a dimple in a header tube?

[spederman]

Ive got ceramic coated bassani headers. There is a small spot i need to dimple a bit to clear my K member. Anybody have any tips on how to go about this?

Ive heard heat it up with a torch and smack it with a ball peen hammer. But wont the torch kill the ceramic coating? Will the header tube dimple if i just smack the piss out of it with the ball peen hammer only and not use torch heat?

+1 with the press, I would not heat it up. If you don't have access to a press and have to use a hammer, put a thin piece of rubber between the metal and the hammer, such as a bike inter tube to help soften the blow and keep the hammer from skidding off the round tube also you don't crush the metal on the first hit.
