raised ports?

what kind of cam .
Anyone can add displacement-I was hoping we could exchange some real ideas what was actually done,
What actually worked in the details, not the globs of added parts so much to get more power.
I did my best to show an example above, - detailed example.
Your tricks ?
1. in the head.. depends on the build
2. If u got em, use em. I don't weld heads.
3. somewhere between 1.62 intake to 1.82. (haven't lager port sizes as manifold head junction changes) Throat, 89 to 92% valve size
4. depends on the build. Don't like mouse cams.

Only tricks I got is use a flow bench, taper cut 7 mm guides in the head (they don;t have any taper in the port side) with a goodson trimming tool.

I'd say you'd need to bound your question more succinctly.
