The heads are 365CNC's which prob only flow the same at our cam lift as 270's would do on a 505/511 with a 650-ish cam for one. The added cubes just makes it a real easy on parts low revving true pump gas 91 motor that puts out 700hp with a restrictive carb in our case. Torque was somewhat low agreed, everything is way off with that combo really but it did ET what we wanted and better in our junk and it was ready to drop in. Its just an example of another way to go for added info really nothing more and perhaps not answering the ops question. I know a few who are running very similar mild combo's like this in the US.
