stealth heads vs edelbrock heads

My Stealths are 2 yrs old I had them conservatively hand porter, a serdi
Valve jobdone and flow benched. Before the vj the low lift numbers
Weren't very good. ( I don't have the sheet here) but improved
Dramatically after! End result was really good 400 number,290ish at 500
And 304 at 600. Exh was in the 200 range over 500. Not the
Best heads out there but I'm happy. In hindsight. I would have put a
Few more bucks with this investment and get the cnc version
