I just got the car running a couple weeks ago and the valvetrain seems awful noisy to me. It's mainly a stock motor with a comp cams nx264hr cam and ported e7's. I had the heads decked and all new valvesprings etc. put on by a head shop and I bought some used roller rockers off ebay (stupid). I think they are harland sharp, they are that burnt orange color with the shaft connecting the intake to the exhaust rocker. I tried searching the forums for info about checking if the pushrods are the correct length. Most of the threads talked about stud mounted rocker arms but I have pedestal mount and was just seein if anyone could specifically tell me how to check the lifter preload to see if the pushrods are the correct length. Thanks
