Simple header question...

[1966-C20]

First of all, nice site. Some of you guys have rediculous trucks! Wow.

Here are the details:

1966 C-20 w/283 and 3 on tree and 78k orig. on the clock
Basically, it is all stock. My work truck.

My question is this:
Cracked manifold on left bank and looking to replace with something better/more permanent and LESS RUSTY. Don't want to spend the $$$500+ on name brand stainless headers so have any of you used these cheap ebay headers?

Particularly looking at these 2:
Huggers:

And these:

Just speculating here, but, the huggers look like the least amount of re-work I'll need to do in order to mate up the existing exhaust work (straight back duals). But my concern w/ these is the motor mounts. Will I have to bang on the headers a bit w/ my ballpean to clear the mounts? Chopping up mounts is a no-go.

Let me know. Thanks guys.
