Ported Magnum Heads, Pushrod Pinch Removed

Without before and after numbers from the same bench you are throwing darts at a dart board.
So regarding doing port work, the only way is to either have a flow bench, know how to use it, or have someone do the flow work or it’s just darts being thrown at a dart board period? BS. That really sounds like just another hard core racer pissing on the parade of someone on a different level than you. Some of you big time guys have to remember how you did things prior to benches, data loggers etc. One can research, read, study, use some common sense and see positive results. It has been done, it is still done. :mad:
