Yes, he installed the rockers, I'm double checking them tonight before I take it for a ride. Nice that the valve covers come off without taking the headers off. I will never take it back to that Marina

Well with the spark plugs tight and the one replaced we hit 68.7 on a GPS with a 23 pitch mirage plus at about 5200 RPMs.

thanks for your help guys!!!!!!!

Great news! What a pain you went through for such a simple problem. Find a new mechanic and have fun.

Thats very simmilar performance to what I'm getting.I just had a friend who had a zz 502 die due to reversion.It droped a valve, but I should mention he wasn't using good manifolds and inconell valves.He also didn't have his cam modified in the maner mine was.I'm hoping mine stays together but you start to get paranoid.
