Yes,i second Tom's thoughts on your Cam 7 lifters,CHUCK THEM before you wipe the cam & lifters out contaminating your oiling system with bearing material that will score your crank,rod/main/cam bearings.
But if you just cant do that and want to take a chance i would check all the other lifters and chuck any that are not very smooth & glassy looking on the bottom/s.
Then i would inspect and lobes on the cam that had suspect bad looking lifters for signs of bad wear pattern/s etc .
If you found any suspect or bad looking lobes give up at that point and pull the cam and lifters for replacement,it's a must.
But,if the lobes looked ok that the suspect looking lifters came from i would re-install the good lifters on the same lobes they came from and apply moly cam breakin lube to the all the lobes and lifter bottoms before reinstalling the good ones.
Then i would buy new lifters to replace any of the bads ones and also apply moly lube to the lobes they are to run on the the bottoms of the lifters and install them.
Then i would pour a qt of gm EOS or crane engine breakin lube over the lifters & cam before you reinstall the intake.
Now you should use the std cam breakin proceedure when you fire it back up again and cross your fingers things work out.
