Smoke tires not drugs

I'm not too sure what your build is, but I know it's not stock. I would recommend you use a pushrod length tool before you either reuse the stockers or buy new. Save yourself the time and do it right. Even if the stock size is correct, buy hardened as mentioned above. Eliminate weak points, don't create them.

A spring to control a lobe with 0.565" lift isn't going to play nice with a stock pushrod for long (hardened or not). 1-pc chromoly pushrods are only $100.

so how do i find out what i need?

That's a good start, sir. Good luck!
