They sure will. GM shoulda been whipped for those aluminum/plastic timing gears!

Be aware that all the shredded plastic from the cam gear ends up clogging the oil pick up, so if you can remove the pan and clean the pick up screen real good or just replace the oil pump and pick up w/a new one. You don't need a high volume pump for a mild build, the standard volume pump is fine.
