That will gain some horse power. I don't know the valve size of the 265, but these mods for a 218/230 give the engine a lot more torque, so talk with your machinist, maybe there are valves appropriate for the 265 when you do the rebuild especially going to dual carbs.
Swirl finish SS 1-1/2" intake and 1.600 exhaust valves using the chevy keepers and port out from 1-7/16 and 1-1/2 valve size – source Engine Pro - SI - Stainless Steel Performance Swirl Polished Valves (rpmrons.com). Match the intake/exhaust manifold to the port as well.
