L98 Vette Heads

Does anyone know how much a stock L98 Vette Head (alluminum) flows at .500?... and how much it can flow fully ported...?

Pro, the L98 heads flow 200CFM at .550" on the intake unported and 230CFM ported with small valves. If you install large valves and heavy porting you can reach 246CFM at .550".

I've got SDPC's L98 flow numbers up on my website. Click on the "Phase #3" link on the main page and then on a cylinder head picture from there.
