Alrighty then
BBM port location, as with Barry a quick stab with the vernier.
Intake
Deck to roof   Port width   Port height
2.900            1.430          2.200

Exh
Deck to roof   Port width    Port Height
3.465             1.370          1.985

That may be a doable deal Barry.
Maybe even do a shoot out?
Mine of course would need valves set. ::)
Oh ya international shipping too just to make it fun. :D

FYI - I'm adding data to that original port position list...

I went out and measured a few heads.  Probably should expand this list to cover everything I see - as time goes on.

Measurements are approximate.  If the OE castings were decked it will change somewhat (obviously).  Castings are also somewhat variable in dimension.  I just stabbed them all really quick - your mileage may vary.  The CJ heads get lots smaller as you go further into the port - tapered floor.  I tried to get just inside of the entry chamfer when present.

ID                       Deck to roof    Port width     Port height
Survival as cast    2.900             1.490            2.160
Survival CNC        2.950             1.725            2.250
Edelbrock as cast  2.785             1.385            2.065
Edelbrock CNC      2.940             1.580            2.300
D2TE-AA              2.725             1.350            1.850
C8OE-N  (CJ)        2.790             1.350            2.330
Blue Thunder MR   3.200             1.540            2.380
BBM                     2.900             1.430            2.200

any idea where pond heads fit in on this list?

Somewhere around the CNC Edelbrock head.  I have a set here, but they're on an engine.  However, I use the same Cometic intake gaskets for them as I do some of the larger CNC ported Edelbrock heads.  They would not work on a small bore, but if you have a larger bore, they work really well, especially on the exhaust side.  Usually 340-350 cfm on the intake and 260 on the exhaust. 

I flowed a set of Barry's heads here, as I purchased them for a customer's 511 inch build.  I bought a CNC ported set and asked Barry to flow them before he sent them so we could have an idea of how close our benches were.  Barry used an SF600 from a local shop to him, and I used an SF600 from a local shop to me.  On the exhaust side, we were within 3-4 cfm of each other if I remember correctly.  The spread was a little more on the intake side, but I tried several different bores, as well as different entry plates and valve prep. 

I did a write up on the other forum and can cut/paste if anyone is interested.
