Heads
I picked up a pair of heads for free yesterday, my buddies mom was cleaning out the garage, and I was wondering what heads they are and if theyre any good. The casting number is 10239906. I have a carbed 350, its a '77 and the heads are stock. Are these heads worth keeping? They are practically new. Thanks

Yes, worth keeping. You need a Vortec-specific intake manifold to use them. It's best to get the spring seats and guides cut to take upgraded springs for more valve lift.
