Valve train noise

Insstalled lunati 60403 hydraulic ca in a 392 stroke 318 based engine with rhs heads. It runs fine, but the valve tr ain is noisey. Right now its just the stock stamped valve train. I dont have any extra play money for after market rockers yet. But with that size of cam do I need them . is it normal for stock rockers to be noisey with this cam. It sounds like a lot of ticking . I followed the cam break in procedure, an the guy from indy set the valve spring pressure up for the 60403 cam with 1.5 rockers. Even if this cam is to small to require after market rockers will having after market rockers get rid of the ticking. The cam I took out was a small comp magnum hydraulic an it didnt make any valve train noise. Thanks for your input
