Aftermarket Valve Covers

[RandyP]

So it seems my new crate engine has a cracked valve cover, hair line crack. Cracked none the less. GM basically told me to get bent, so I'm thinking of a set of shiny chrome aftermarkets. I noticed the stock ones have baffles in them, do all the aftermarkets have this as well? Plus I'm having a hard time finding any that have one side with oil filler and a vent hole, and the other side having a vent for the PCV valve. Starting to wonder if I really need the vent from the valve cover to the spacer plate on top of the TBI or not.

87 R10, 350 GM crate engine (not center bolt, old school motor) with TBI intact (for now). Gimme thoughts or suggestions. Have never in my life put aftermarket valve covers on a vehicle, always kept the stock covers.
