Our 1st test factory Magnum heads

IQ, how much work, if any, did you do to the pinch? Everytime I look at a Mag intake port, I always end up shaking my head.....lol. People have tried to convince me that it's ok, and the stock # do look pretty good, but I'm still having a hard time buying it. Would love to know your thoughts on that. If anyone could convince me, it's you. Thanks, Rick
