Let's talk CAMS/SPRINGS/PUSHRODS

Had my 5.9 swapped 70 dart going for awhile now. it's gets beat up pretty good. 750 carb, airgap mani, headers, mallory hi fire box, 4.56 gears, 904 trans. anyways, seems to have developed a "miss" believe on the #8 cylinder. did compression check, was fine leak down wasn't bad but did flutter a bit. Think maybe I bent a pushrod. anyways, if so, may as well look for a cam/spring pakage. keep hearing horror story's of bent pushrods ect, what has worked for yall? Don't need anything to crazy. but need an upgrade.
