Re: 1 bad lifter options ...???
If the motor is a junk 2 bolt main with cast crank and pistons that you just want to live a couple more years. Go ahead and just replace the cam and lifters. If it's more than that or you want it to live for many more years. Tear it down and get all the metal out of it.
