Never bothered me much. Grind the pocket and grind off the pops... no sweat. The real gains are elsewhere as you know. Getting those nasty hotspots off the corners IS all one really needs to do there on the big dog v4 and V6 motors.
The little dogs, like the 25hp, polish the in cylinder bits and attack the reed cages with a diet plan. 40* wot vs 26* stock. Never even put rings in that motor. I did put a bigger ported carb on it and that was the magic touch in the end game tuning it.
First thing on little V4s is to swap the heads and exhaust plate to 135 or 140 chit. You can't keeps rods in those motors anyway with those heavy slugs.
76' Rude 115 hurumft... come and git some but hang onto your hat!
Or a 135 ported but you got to stay under 6,500 or chit goes bye bye right out the side
