Bought these brand new over the winter, went to put them on and I had a change of heart and put the original ones back on. Brand new MQQN finned valve covers, never on car, I put on extra fat cork gaskets with RTV, and blocked the breather with RTV on the pcv valve side, and just didn't install them. I bought them for 420.00 plus shipping. I will sell for 350.00 shipped in lower 48 (that's about 100.00 for "free"). breather has a little scratch on the bottom (wont see when on engine), not certain why its there, only noticed it while taking photos to offer for sale here.
