They are plain Throttle body injection heads,i've got a set and they came off a 88 model suburban.I can't find any specifics on port volume but i know the cc's are around 74.

i was thinking they were 64cc heads.

i wouldnt bother using them, unless you do a lot of port work to open them up. I believe they have the ramp in the intake runner to 'help induce swirl' that really restricts airflow above 4500 or so.
