Reply to "351C cylinder heads, open chamber vs closed chamber"

Thanks George,
I definately have the large port heads - I've removed the intake manifold in the past.

Are 4V open chamber heads the same as Cobra Jet heads?
Does a late '72 motor mean I have a 4V or a Cobra Jet and what is the difference?

I've no history for my engine. I think it's stock, but it had a 700cfm holley 4778-2 and an Edelbrock Torker when I bought it so who knows...

p.s. I got a couple of heads in the garage that look very similar to the closed chamber head in your picture. They are from a Sunbeam Rapier - though these were used with dished pistons.
