Anyone using Dougs D453 headers on Magnum heads?

How far down do they hang in relation to the trans (auto) pan mating surface? Liking the looks of these, I want as tucked up as I can find.
Here are some picks of mine, car sits low and has some rake, using bisket type mounts 15 inch rims with 205/65 front ,rear 245/60 but no scrapes over speed humps. Sorry about the shitty pics but it gives you an idea.
