How loud are roller rockers supposed to be?

Ok when i had my new engine built i went with a CC305 cam, Crane Gold Non self aligning roller rockers and hardend pushrods/guide plates and crane lifters.

Now that the rockers have been adjusted twice and the motor has about 200 miles on it. I can still hear them inside the car with it idling and all the windows rolled up. radio off.

When i am driving beside a car on the road i can hear them tick a little too. Are they supposed to be this loud?

Both times they were adjusted with the car running.

Mine do the same thing but i'm using 1.6 R/R CC pro mag. You just have to get us to a new sound. I'm still getting use to the new cam sound.

Yeah they are 1.6's. I guess they are just supposed to be noisey. It's not too bad though.

thanks
