[DeTomaso] More valvetrain for 6143

In the first photo, It almost looks like the lock nut is hitting the rocker arm? 
I can see plenty of clearance on the #7 intake but not on #8.  The roller tip 
must be allowed to sit flat on the valve tip and roll across it as it pushes on the 
valve. I would bar the engine over and inspect every rocker arm as it moves. 

Also, I'm not sure which valve covers you have but you need a way to deflect the 
oil from the push rods back down into the roker arm.
