Proper Procedure
As soon as the engine fires, bring the rpm up to 2000 to 2500 during the first 30 minutes of
operation. Slower engine speeds will not supply the camshaft with an adequate amount of oil for
the break-in period. The engine rpm may be varied periodically from 2000 to 2500 to direct oil
splash to different areas of the camshaft. After the 30 minute break-in period, change the oil and
filter again to be sure all contaminants and break-in lube are removed from the engine. The inner
valve springs should now be replaced and the correct rocker arms installed. http://compcams.com/Base/pdf/FlatTap...chBulletin.pdf

yea. only flat tappet cams need breaking in. only reason is because the only lubrication the lifters have is slung off the crank. they need to wear in properly
