Another lifter noise question

I'm pretty sure I'm going to just tear it down this winter.The blood disorder I've got is terminal.They can't tell me how long I've got,5,10.15,20 yrs maybe more.Just don't know.So I'm going to live for today.Was going to stroke it but I think I'm just going to put a better set of rods in it,put a set of heads from IMM on it and get it balanced.The guy who did the machine work said it wasn't neccessary for a driver but I'd like to do a little racing.Plus if my health care costs make it necessary to sell the car,sure don't want to have it tapping away.
