As much as I hate to disagree with you on this I have to on this subject. I Dont think I gave up any thing high, mid, or low on this port. Sometimes I feel guilty telling guys not to aggressively lower the shortside on these heads because you have to. BUT and this is way I say it. You can mess up a port real bad if you Dont know the needed steps. I take caliper readings off my deck across the top of the shortside and have measurement’s for a 290cfm port, a 311-315 cfm port, and a 320 plus cfm port. You would be amazed at the shaping necessary.
