Quiet when cold, sewing maching when warm

I just put track heat heads and trick flow 1.7's on my 94. I got the valves all adjusted correctly, and have even checked it a couple of extra times just to be sure. Im just wondering if even after I've hammered the valve covers, if the roller rockers don't expand with heat and start barely tapping the valve covers. Has anyone else had this problem? Thanks, Will
