Cam & engine gurus gtf in her meow!

Surprised nobody recommended a custom grind. Is there a cutoff point to when one is and isn’t called for or something? Not a common option but how about in the 258-264 advertised range and slap em on a 106 LSA, use a faster “lift limit” lobe or? (since no specific size lifter has been mentioned I assume anything goes?) certainly someone could spec out something to suit for the guy, better than compromising with those dreaded shelf grinds!
