Checking the cam timing at 0.020" lift is almost a waste of time.Check it at 0.080" lift.
0.020" lift figures are not reliable.If they happen to be accurate,your intake lobe centre is 106.5 degrees:advance it 4.8 degrees and it will run better.
112.5 is a little much on the exhaust.If the 0.020" figures agree with 0.080" figures,retard the exhaust 4.8 degrees.
Well time will tell, not every one is an expert and, experts are sometimes only in their own mind! Further to that, I trust my Guy, he has ground more cams than I have had hot meals, cam timing to him is second nature. He was not the least bit interested in mucking around with .080" and did it his way. All I have read on the net is"020" is all good.
Not changing anything, and as above time will tell!
