.600 lift??? Seems very high to get only 212cfm/175cfm. I had mine ported and at .525 lift I was flowing 225cfm/185cfm. How much is he charging you for this port job?? Mine cost me about $900 to get pocket ported, gasket matched, and all stainless steel valves installed.
I ran the 270H cam and was sitting right around 400hp with 225cfm/185cfm and total lift was .532/.532.
