Those have 68 cc chambers per the description.... better make sure than chamber works for the intended CR. They would lose 0.5 points of CR in the setup I was looking at them for; not what I want to give away for the application.
65 or 68 would be acceptable.. 11.2:1 with 68, 11.6:1 with 65. I'll double check them, but I think they post 68cc as if the chambers are cnc'd as well and so far all of the pictures I've found the chambers were as cast. Either way I'll make 'em work.
