MG Sports Cars

I know this subject has been gone over many times but it still baffles me!!

Are there any commercial header manufacturers besides Fast Cars that provide a through the fender set of headers that will fit a 302 and can be modified to work with the MGB configureation? To help assist the header install process, my engine mounts will attach from the engine heads to the frame rails thus allowing more room to work with. This will also help in the steering as well.

I know Fast Cars offers them but I've seen people use a Hedman model or make their own. I suppose I could make my own but I don't want to go that deep unless I have to!

I'm not worried about the modifications to the body as that really isn't a problem but I'd like to know what model number and commercial manufacturer might have worked for others in the past before I try to wiggle in something that has already been tried and doesn't work.
