Few questions on these heads These look like the same heads w/ the exception of the Vengeance pieces having Manley Valves and better springs, am I right? Which would explain why they flow a bit better?

The vengence heads are actually Scoogin Dickey heads.The difference is the valves and the cnc programs used are different between the 2.I'm running the SDPC (vengence heads) and made the same horsepower another gto with identical build except he had a custom cam and mast heads.
