I'm wanting to ditch my OLD low hanging headers, are these manifolds worth it?

Hedman block hugger shorties, or 68-71 340 HI PO manifolds. Either way they are gonna cost you. They now make repop 68-71 340 manifolds. No factory markings though. About $600 new.
The Hedman shorties are a little over $300 with FREE shipping on Amazon right now. Close to 1/2 the price of the HI PO manifolds AND I've got to factor in shipping to AK!! Trying to stay within a budget....
