rocker arm advice

Hey guys looking to replace the rocker arms on my 68 Cuda 383 4 speed.. I rebuild the engine last year but left the stock rocker arms. Still hearing a bit of valve train noise, so thinking possibly rocker arms. I ran the comp cams #1621-16 adjustable roller rockers in my last 440 but are pretty pricey now.. was thinking either HD stock rockers or comp cams adjustable rollers agian... any advice?? Thanks
