What is the thread pitch for the rocker arm bolts I need to know the pitch of the threads on the rockers arm bolts. I am thinking 8mm x 1.5 or 1.25 I need to know casue I need to get a helicoil for the one rocker arm on my car. I pulled all the rockers off to reseal the rocker arm bolts on my PP heads because the car has been smoking alot since I got in rocking after this last build. And when I went to reinstall the #2 intake rocker it started to get snug and then popped. I removed the bolts to find the threads stuck to the bolt. 
But I think this was my smoking problem anyway becuase I pulled the intake now and found oil on top of that valve and none one the other valves. I just need to get this fixed now before I go to get it tuned friday.
