All of them are to my knowledge. 



Are any of the after market aluminum heads squelch area heads?
Thanks,
Ken

Joe is right, the small valve 915 heads came on the non-magnum 440 C body
cars and Imperials in 67. I think everyone misses the real issue with 915 -
516 heads. Yes they will produce a higher compression ratio because of the
chamber, but the chamber is the real advantage. A 906 head has some small
inherent flow advantages, but the open chamber is not a squelch area
chamber. I am including a great link to the first of three cylinder head
articles. All three are a good read.

Earl,


There were low performance 915's with the smaller 1.60 exhaust  valves.
And
I think if you open up the 516's to the larger exhaust you  have about the 
same head, although I don't know what they flow.   Joe
