Best headers for truck with 350?

[Jobe72]

I have an almost bone stock 72 GMC with a 350/350 combo.
Blew a head gasket and putting rebuilt heads on.
Both exhaust manifolds are cracked, so decided to do a few hop up parts.

Already have an HEI and Edelbrock carb, going with a Performer intake, upgrade to MSD HEI and thought I would put on headers too.
I already have full dual exhaust from previous owner, will have to be modified a bit.

What headers fit our trucks the best? had an old set of Hookers on my 72 years ago.

Thanks
