We needed to add some better engine breathing on our LS1 on the CP Firebird, so instead of hacking up the valve covers we had, we got some tall OEM style covers to modify. The breather system works well, so we'll never go back to the old system. I have the take-off GMPP Pontiac valve covers for sale. They are lightly-used, but not abused. We had them on the car for a year, or two, before pulling them off. They've been in a plastic storage container ever since.
I'd like $400 for them, since they're NLA, plus the ride. They'll come with the bolts, push-in oil cap and used, but good, gaskets. Thank you.
