New Magnum heads for 347 with Flow data

You made note of the Crosswind somewhere before - I can't recall if it was this thread or elsewhere but I remember you commented about the Crosswind and Air gap being close to equal. I've only used one that was not equal in performance (economy and "butt dyno" power suffered) and will avoid them now for a bunch of reasons.
Do you recall the setup that lost power as a result of port matching? Was it a problem with the matched intake and anotehr substituted that made more power? Was matched vs non-matched a planned test I guess is my question?

Yes it was a planned test. I dropped a Performer RPM OOTB on a 360 and tested it. Results were quite good. I thought if that was good then taking the grinder to it would be better---Wrong. It lost about 5 ft/lbs avg-2500-6500 rpm. This was not one pull but many and the trend was very real and apparent. J.Rob
