All, my stock FD2 had relatively high camshaft wear hence I switched it with an identical pair from the same model and make as my car. My mech also verified that it bolts on perfectly but pointed out what I am also about to share.
Its been months since its install but the following has been bugging me. The surfaces I have circled out are very different, even my mech said it looks and feels different (when you run your hand on it) to the stock ones I had on the car. Can anyone clue me in on this?
I am unable to find an explanation.
