New Magnum heads for 347 with Flow data

True.
For the most part I get about the same as most, but Hughes must have a a mouse hole in the bottom , that or theirs is the end all and we are all full of it.

Mainly something to consider aside from that is honesty in prep, are the heads really untouched ? 3,5,7 angle valve job? What valves? Sunk? Chamber unshrouding cut?

When I see numbers from anothers bench fall in line with my own, consistantly, for instance 3 vendors here have posted numbers damn near identical to my own testing ...it kinda shows they may have a problem on their end.

Yeah Hughes's numbers are "out there" lol along with many others. Seems like everyone in the cylinder head sales game is guilty of pushing inflated BS numbers in my book.
I was in an interesting test years ago. Myself and 2 others ran a flow test on the same head same port. The bench was a Super Flo 1020 with a Brzezinski fixture. Each of us setup a clay radius entry from scratch for our test. Each of us got different numbers (8 cfm difference at peak). My clay adapter flowed the lowest, guess I wont get a job at Hughes or Indy. We then built a .75" plexi inlet which actually had the lowest flow of all. Absolute consistency and repeatability, just low. This head was then tested on another 1020 bench with the plexi inlet which yielded different numbers yet again (higher).
Ever since this experiment I haven't put much stock in comparing flow numbers ie bench racing.
