3998993 heads....need work....$50 for both DFW - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I took these off my 70. There's one valve without a seat on one head and one with a really bad valve guide and three on the way to going bad on the other head.

Pickup in Terrell or East Dallas [m-f 9am-3pm]. Shipping will he high due to weight, but if you send a zip I'll let you know how much to get them to your door.

A lot of racers are making 2.02 heads out of these...currently the valves are 1.94/1.60's. These are stock heads with a valve job on them. I'd say all the guides will need replacing and at least one valve.
