I really hate to comment on other people’s work. Mainly because lighting is so critical in seeing what is going on. No only my porting bench but my shop looks like an airport lit up at night. Close your eyes and run you fingers from the carb flange down each runner and down the vanes. Think radius while entering the runners. Would a short turn like a 90 degree turn (I don’t think so), thinned vanes but not sharp edged, no humps, divots, etc. the hardest thing about porting an intake manifold is getting it in the 36 different positions to get it right. I have V-blocks, different sized chunks of wood, and things to lean it against.
