700 bucks a pair, are they like the extreme ****tiness? or do they flow on par with GT40p's but 50 lbs lighter assembled?

lighter weight, bigger valves, and more flow.

ok heads but there are better ones. for 300 more you could have trick flow heads which are worlds apart from these.

here is a comparison on the flow numbers. iron head link at the top of the page.

Take off head means they were taken off of some new motor. I read that as used. They might have never even been fired, but they are used heads IMO.
