I agree. I’m just not willing to ruin anything nice. I learned so much about fluid dynamics working on the bottom of my boat and it opened my mind to how much I don’t understand about how fluid (air is considered a fluid) moves.
I have a simple theory with this set of heads since the started out good. Measure them, keep the shape & enlarge that shape where necessary.
I'm not going bigger on valve size, however I'm tempted to use a 2.250 intake (cost says nope)
So I won't be doing much in the bowl area except sanding out the CNC and adding burr finish boundary layer.
I think about that fluid dynamics stuff myself, I used to a lot since a river almost killed me and the ocean did the same.
1 thing I know for certain...gender is not fluid lol
