Old cam will chew out new lifters in no time

Excuse the inexperience with this stuff, but will it still do it even if the cam isn't damaged?
Going by what the mechanics have said that I've talked to, it may only just be the internal bits of the lifters that are not self adjusting to suit the rpm of the motor, that'd mean that possibly there is nothing wrong with the cam.. and if that's the case, would it still chew new lifters out? or would they be ok for the next 9 months until the V8 gets fitted??
