a set of chrome 400-430-455 valvecovers I'll let go for $85.00 + shipping and they have one chrome breather for each valvecover. Can do PP. Also not stamped. I just put TA roller rockers and the cast valve covers on my 462. Shipping should be around 5lbs. Email is best. They clean up lik new, no dings or scratches. Just like the ones quickstage1 sold. Also listed on Ebay
