You hit the nail on the head, had my share of motors claimed (12) when I used to run IMCA and NEVER did a guy claim one of my motors and beat me with it.
Speed is in the setup.

Why don't you go the extra step and find out what the manifolds actually flow so you can determine fr yourself what is better. I am sure there is a good head porter with a flow bench in your area if not it only costs about $25 to ship a manifold anywhere in the country maybe $50 if it is far.
I flow 3-4-5 manifolds a month, sometimes more sometimes less. I charge $100 to flow all 8 ports. When you have a manifold restriction it is critical to get the best head flow you can. Do you know where you are there? I have recently flowed some EQ heads and have a valve job profile that kicks the flow up on them pretty good.In my opinion you are wasting your time with those old cast pieces, they weigh a ton and unless you had someone really good work on them they won't be much better than stock most acid porters don't take material out in the places where it needs to be removed and I have flowed many a $1000 cast iron manifold that was worse than a stock one. Airflow does not always like more volume as it can kill the port velocity.
What is the penalty to running the 2701???
I have been selling a bunch of 602 parts to the mid-west since the first of the year. I know I have some 602 crates here in the SE that can hang with stock 604's so they would definitely blister IMCA built engines.
