Roller cam valve noise

I have a 302 HO roller cam block with a truck flow cam and truck flow aluminum heads with around a 550 lift, I have a valve clatter right off idle, reset the valve lash (hydraulic roller cam) with no change, I have read that a aggressive cam with the stock "dog bone" lifter setup will make some noise, I just ordered a set of "linked" roller lifters and am going to give that a shot....I will post my results

Valve train noise is not usually confined to a certain and very specific specific rpm range, especially if it depends upon load. Are you sure it's not common off-idle or "tip-in" detonation (pinging)?

Re: Roller cam valve noise

Monty: Have the same issues with a clatter, from valve train so I thought, pulled the factory dog bones went with Comp link bar style
I;ve still got that clatter until I get up to temperature,(175 +) its virtually gone.
With the stock set up, I never really got the motor up to temp, so did the lifters solve my issues? not sure
