i just got put in new crower camshaft, valve springs and retainers and supertech valves in the head. and just a cuple days after driving it, it started to make a loud chattering sound like its coming from the head i think. the mechanic set everything to honda specs when u put all that new after market **** does it have to be set at difrnt specs?????

 

99% of the time when you replace OEM parts with aftermarket it will come with new lash/ torque specs. Most cams are like this and ARP headstuds are the same way.
