Not unless you send them off and get them reground. Used lifters are worn in mated to each lobe they broke in on. If they are removed and not kept with the lobe they broke in on, you might as well throw them away. Having them ground will cost as much as new ones by the time you pay for grinding and shipping. BUT, you can run new lifters on an used cam. That's perfectly acceptable. Get some new lifters.
Lastly, and I am not trying to be an asshole....I am very serious here. If you're on such a strict budget that you're thinking of running used lifters, maybe you should wait on the entire project until you can afford to do it right. The last thing you need to do is assemble it half *** and have it come apart and ruin such a fine core. That would suck big sweaty nasty *** balls.
