Selling a pair of billet valve cover adapters. These will allow you to put pre 86 covers on centerbolt style heads. They are practically brand new. They have been sitting in my garage for a few years now. The O ring gaskets are no good anymore, they are dry rotted so you will either have to get new O ring gaskets for them or use regular valve cover gaskets. I also cannot seem to locate the bolts that came with it but Im sure any local hardware store will carry the correct bolts. GM might even have replacements. The GM part number for these adapters is 24502540. New they are $150. Asking $80.

The gaskets are GM#12480023 and are about $6. Good luck on your sales.

pm sent with my number. please give me a call.

I am no longer pursuing this purchase, they are back up for grabs!
