i have the port and polished heads with the full race valve train installed too....I showed a little while back..i also have the exhaust manifolds ported....now if we could get some Pentroof manifolds on and get the blocker plate where the exthernal WG bolts to I think we could see some very high HP gains with just those manifolds alone!....I am waiting patiently and I know with the setup I will hit over 600rwhp....i will post charts asap!
