1971 Duster 360/727

Rumblefish: Alright I think I got it now.
I have no idea if he is good at what he's doing or not, I only know that he's had the company since -91 :p He also said that with the bigger valves you lose torque and you need to rev higher which is bad with a cast iron crank.
Don't really know what my goal is either actually, im not gonna race it or something like that but I want a "fun" street car.

I will check those rockers, but what is the difference between roller rockers and ordinary rockers?
