Valve job on os valves

SOry for the multitude of posts recently but i am rebuilding my head and converting to a super six currently. I was wondering if i should get a multi angle valve job with my new oversize valves. they are the 1.7/1.44 valves from orgen cams (just up the street) and if the hp gains are minimal or with the cost.

Short answer,Yes.
More detailed answer, ask if they will add a 4th 70 degree to open the throat to size for the 1.7 valve.
Gasket match the head, port the floor from the window in about a fat inch ish..then quick roll down/decend into the floor about .060 ish straight/toward the valve...then go from the bowl side and work the ssr to the floor work...that's your new and improved short turn. It will have 3 parts, entrance,runner, desension ramp.
