Starting a rebuild of a 65 Fury Convertable with a 383B engine. But I've got a question about the heads. There's two intake ports on each end, but there's a hole in the head in the middle that doesn't match the intake. Is there supposed to be some seal over it, etc?

That is a port to allow heat to escape from the hot exh passage that runs thru the intake , it's supposed to be open and exposed .

Thanks. I've just never seen that on a head before, and with the issues we've had with this resto (got someone else's project), especially the engine, just had to ask.
