516 head rebuild

I'm been doing some reading and I think I want to just ad some guides clean em up and dont do much more to em till i change the heads later. right now I'm just wanting to get the big block running in my duster and do some burnouts and drive it. Not looking for anything extravagant but good sounds and burnouts
Why not just knurl the guides. That's what I would do. lap the valves , add umbrella seals and run it.
until I saved for a good set of aluminum heads.
dumping money into a set of 516 heads is counter productive.
