"Yup, raced the GN at the track a couple weeks ago...I was well on my way to a 13 second pass on only 15 pounds of boost.  between the 330 and 1/8 I lost power and new something was wrong so I backed out of it and coasted her in.  I had a ticking noise on the driver's side valve train and figured I collapsed a lifter or bent a push rod.  What I found I was not expecting.\r\n\r\nI finally got a chance to pull the driver's side valve cover and found the forward-most rocker had busted right off the shaft.  It lifted so hard it bent the el-cheapo grade five bolts the previous owner used on the hold-downs.  I may have over-revved the motor, though my chip indicates the redline is set at 6000.  I'm not sure how the rocker could have lifted so hard like that unless I did over-rev the motor. \r\n\r\nAny thoughts?\r\n\r\nWhat rocker assembly would you guys suggest?  My mods are in my link.  Be advised my next upgrade is an alky control kit, and I will be laying more boost at it...maybe 20-25 depending on the tune.\r\n\r\nThanks."
