If you haven't heard of "Singh Grooves" it is another twist to get you thinking. If I built more engines I would think about trying them on one of them.
several folks played with those squish grooves years ago.i cut some too, didnt hurt, but was no proof that is helped as i recall. it was kinda considered as something to try. best advice i can give is to round the edges on the grooves to not create hot edges. about the same time, pent roof was all the rage, that had about the same conclusions. compression and timing nightmares were introduced into the equation and almost no one wanted to play with the $$ to prove theory. i quit keeping up with that, but a buddy does atv stuff. he worked on a kawasaki v-twin that came from factory with pent roof and big compression. worked well, until he bought into the hype of pretty packaging, internet hyperbole and "performance kit"! it always sucked after that. so take all that with a grain of salt.
