I have a civic with an H22A4 engine in it. I tuned it not long ago. I recently bought new cams. When I went about installing them i found out that my stock rocker arms and camshafts were worn down. The surfaces of both were filed down especially on the exaust side. I have JGE springs and valves installed. The wear was greatest on the middle VTEC arms.I am guessing the stock rocker arms wore out because of the springs. I have not seen any performance arms and will have to buy the oem ones. I am afraid of this repeating. If anyone knows the cause of this please advise.

 

If your not too worried about idling issues. Crane and one one other company now make Roller Rockers for the H22 engine. This will eliminate any wearing issues escpecially with Billet cams. It will also lighten up your valve train becuase you will no longer need VTEC becuase it will always be in vtec.
