Which Headers?

Oh yeah, I forgot valve cover gasket "rails" that are raised 1/2" or so to reduce leaks. That can sometime cause a valve cover to interfere with with an alternator or AC compressor.

I've actually had to re-fab compressor brackets, notch frame rails for header tubes, and raise exhaust pipes where they connect to header collectors. And some heads will have spark plug holes in slightly different locations from stock, Vortecs being a good example. But other than that...

My biggest concern right now is how low the Hookers will hang below the frame.
Since I have mid length right now I know the connection to the header will change.
I'm hoping G will take a pic just to confirm.
I have no A/c to worry about and have about 3/4"+ frame clearance with the current Heddmans.
Thanks for the input it really helps!
