I have the black Holley LS valve covers that dont require the coil brackets. I think they clean up the engine bay. They dont have the PCV flow restrictor in the driver's side so they dont work without modifications on a DOD engine. Mine have been fine since I have a DOD delete catch can set up. I'll try and get a better picture this evening.
Proforms. they come with baffles. not mods other than adding a oil cap filter breather on the passenger side and and oil catch can on the other side. both oil cap filter and catch can have pcv check valves
