Good thing I'm not in a hurry! Went to screw in the rocker arm studs, 6X heads, ARP studs
p/n 290-7201. They won't go. Pulled a stud off a set of 4X's I had. The bottoms are not the same size or thread. I thought this was a direct swap. So the Q is Which rocker arm studs do I need or do I have to pull the heads and have them machined
If that wasn't enough the dipstick I've had for 2 years isn't even the right size. Frustrationis building....
