I have some Offenhauser valve covers for sale. These were on my truck which I purchased from Darryl Dier long time member here. After the engine rebuild, they still fit with the roller rockers, but I've had issues with oil coming out of the filler breather area. Your welcome to use them with roller rockers but they really should be used with regular rockers. So I purchased a new set from Offenhauser that are taller and have baffles. These are great shape with a few knicks here and there and some surface scratches. They have one hole for a PCV (will need new grommet) and a twist in breather/filler hole. Comes with two filler breathers that fit. PayPal only and you pay for shipping and any fees. OBO as well.
