its worse than that brother. the stockers are 76cc. My aftermarket 007 heads are 72cc. The double humps from the 60s were 72 as well. the only real difference in my 007s and dh heads are the runner volumes and valve diamater. the 007 are 2.02in 1.60 ex
Double humps from the 60s were low 60cc's so are 193 tbi's and and 601's most double humps will not have late model accessory bolt holes and will have 1.94 intakes .

Ok,,, so what would be a good 4bbl intake for the TBI heads? Sounds like I should keep what I got.
A performer or any good dual plane will work if you already have one,for pre tbi heads or know where to get one free or cheap, to use it ,4 bolt holes need to be elongated with a Dremel or a drill bit. They use to make special washers just for doing this that corrected the angle change, but I know I could make some with a drill and a hacksaw or possibly even just use rocker arm pivots as washers.

Guess im gunna poke n hope when i put them on...
If you want to c.c. them it's easy,put in your spark plugs get a piece of plexiglass seal it to the combustion chamber with some grease. Drill 2 small holes in your plexiglass 1 to let fluid in 1 to let air out now use a syringe to fill the combustion chamber. Easiest is start with a burrette with a measured amount of fluid then see how much is left. You start with 100cc's and got 28 left you have 72 cc chambers.
