last weekend i finaly put in my new cam, comp 224/224 581. lift, comp valve springs and push rods and a nelson tune, everything went to get great i drove it for 3 days then i got a harable noise, i took off the valve cover to find a broken spring, a broken rocker ( needle bearings everywhere ) and probly a bent valve sence its still in the head. any ideas what would cause the rocker to come apart and the spring to break at the same time? i was told the pushrods where the correct length but they seemed lighty larger then the stock ones.
