70 Chevelle LS3 Exhaust Question?

[AZSaleen04]

I'm in the middle of my project and looking for a full exhaust system to go with my LS3 6 speed automatic going in a 70 Chevelle.

I haven't been able to decide if I should go with shorties or full length headers.

What are your recommendations for a full exhuast system? Who make the good headers for this setup and also would like to find headers that can be removed without lifting the engine.

Thanks in advance.
