Hi sissypoo1, Welcome to 2carpros and TY for the donation
id you mike the camshaft lobes before you replace the lifters and also adjust the valve lash?? if all okay-check the valve timing could be off.
Also I recommend you do a cylinder leakage test-if the readings indicates minimum leakage and shows all low compression -recheck your valve timing could a notch or two off-
