Exhaust manifolds, do I need a gasket

Hey all, I'm replacing my rusted thru manifolds with a used, but non rusted eBay set I can get for 40 bucks as opposed to 200 for a new set. I'm going to have them ceramic coated along with my new bellowed up pipes after I sandblast them and clean them up... I will be installing manifold gaskets, and wonder if I need to get the manifolds resurfaced by a machinist since I'm installing the gaskets?

Off eBay for 40 bucks? I'd at least let him check it out beforehand.

Ya the guy has like 6 sets... Don't know if he had a fleet that he's parting out or he's just a salvage guy but 49 bucks a set is what he's asking and from the pics they have minimal rust.

What I'm wondering is whether it's worth the cost to machine flat if I'm putting a gasket on anyways

Put a straight edge on it. If it's perfect use it as is. If it's not perfect, have it machined.

PIS 175/80's, Van Turbo with EBPV, BD Billet Wheel
Lots of money spent at RiffRaff
Holley fuel pump, in tank mods, crappy riding leveling kit, DP-F6, 5 Gauges+Edge CS in dash, CB radio in Dash, over 100 goofy little mods
Still pretty slow, just less slow now.
