Original trickflow highports: What size CC

[tomst9]

I have a set of the original trickflow highport aluminum heads. I'm trying to find out what size combustion chamber they have. I know the nw ones have a 64cc chamber. The heads were also milled .030, so what woul it be then? I'm trying find this out because my car is a complete turd. Its slow as hell and i'm think i might have gone too big with these heads for the 302.
what do you think?
thanks
tom

are these the real old TF heads with pedestal mount, non adjustable valve train and no stamp that says Trick flow on them, and a SN##### casting number?
If they are, they are 58cc unmilled.
BTW, these heads own the new TF heads.

These have no stamp that says they are trickflow heads, and they do have the sn ##### sierial number, but they are stud mount rockers. I really hope they are 58cc
