Head Porter

I have a rebuilt set of 6X-8 heads and was toying with the idea of having them ported before I install them. Are there any good head porters on this forum that do side work? The motor is a 467 with RAIV cam and 9.7:1 compression. I would like to get the intake flow to 240-250 cfm and the exhaust to 170-180 cfm. Valve sizes are stock.
