Sorry for your troubles. I have a first run cobra (received in June 02) developed the tick and had it fixed at 1600 miles. She now has 6400 miles no tick. My mechanic tightened the cam bolts at least 1/4 turn tighter than it came from the factory. It seems to do well(no ticking) and I am happy.
Like the muscle car page. My older brother had a 1970 Boss 302 (Grabber Blue) in 1975 while he was in high school. The ignorant thing raced it and blew the boss engine swapped in a 351 and sold the car. What an idiot. If I didnt have an 03 I would gladly pay $35000 for a Boss. Well enough rambling, just had my apppendix taken out this morning.
As far as I've heard, tommy is the only instance of a problem after having the new head replaced. (Makes me wonder if it was installed correctly? Maybe the timing on one of the cams wasn't set right?)
