I have been reading up on lighter valvetrain components, springs/retainers/valves/pushrods and looking into some options as far as pushrods go, I wonder if anyone here as ever tryed using a diffrent kind of pushrod from what seems to be the standard 4140 adj for most custom builds?, I know that Jims is making titanium HD pushrods now and I found a few interesting sites with some info... thoughts anyone?
