What I like about my Kromer Headers are that they are very light and fit great in an unmolested stocker engine bay. I can get my mini starter off without removing a tube. I can also get all of my spark plugs out with a cut off combination wrench and no other tools, all from the top of the car.
If Holts does Headers as well as they do chassis and roll cages, I would say that would be a good choice also.
