Well you did start a p**ing contest looks like. Why didn’t you just ask the stupid question instead of just trying to insult everyone. I’ve got a customer that needs aluminum heads instead of iron for this build. Roller rockers are expensive but that’s not the real issue. They are just really very noisy. I’m trying to keep the noise to a minimum since we are using a low lift cam and don’t need the adjustablity. Now you know.
