I think the classic 3 cut valve seat consists of 15° / 45° / 60°. Is this right? And what would the effect of having a 30° top cut rather than 15°? Although I guess if the top cut is already 15° then 30° would mean cutting the seat deeper?? Trying to visualize this on an empty stomach..I need sugar! I’m not going for max. performance just trying to get things in decent order.
Hopefully this is not such a stupid question that it will attract derision from "up north"
