Headers and header bolts and wrenches

[boat737]

As said above, it's a common problem. Don't be afraid to dimple the headers a little bit around the bolt head. You won't affect the performance any, and it will make your life much easier. Put the ball end of a ball peen hammer on the pipe next to the bolt hole, and whack it with another hammer. You only need a couple of mm's of extra space.

Hammer's and car's, just don't seem right. That said, Any idea on what will happen to the ceramic coating? and will that weaken the tube at all? Thanks Bob.
