I am currently having my engine built and was curious is changing my 906 Heads worth it for my application. I have the voodo cam 60301 and it's bored .030. I have the HP manifolds as well with a Edl performer intake and 750 holley. I plan to drive mine more on the streets with the occasional horse play and tire burn out. I ask because the guy doing my Machine work is charging around 3 cenos for the 3 angle valve job and all. And if I had the 906 ported a little would that be equal performance to the stealths? Just curious.
