First off I have to say my new build runs awesome 103, stock pistons, Veetwin performance street port,10:1 compression, Crane Cams chevy lifters, SE non tapered pushrods. I adjusted my pushrods 3 turns down and the valvetrain noise is obnoxious! The motor runs smooth as silk other than the noise. The power with this setup is really cool! I'm not sure if I'm bottoming out the lifter and need to loosen it up or try tightening them a flat at a time. Any help is appreciated. Thanks.
