I bought these for my IROC because I thought the tall design would be an advantage for me with my new roller rockers but they're causing too much trouble with all my wiring and coolant lines so I'm going to try and run regular height covers with perimeter bolts instead.
These are ball milled, polished, baffled, perimeter bolt valve covers and are great pieces. They are very solid compared to factory stamped pieces and have an extra thick rail on the bottom. I paid $130 for them and would like to get $120 back since they haven't been used at all, just test fit on the engine.
Here's a link to what they look like.
