Not sure what your asking? If you had a lobe go flat, all you can do is start over. Tear it down, clean everything. install a new cam and lifter. Make sure you coat the lobes and lifter bottoms with a good assembly lube. make sure it fires off as soon as possible and break the cam in at 2-2500 RPM for about 20 minutes. Occasionally hit the throttle during break in. Use a high zinc oil or additive in the oil.
