Yep. That's 0.2". Doing this allows the studs to be bottomed on the block holes and still clear the valve cover webbing.

 

You caught my post before I deleted it .

I didn't know it was 0.2". I knew there was a 2 in the dimension somewhere. For some reason, 0.020" came to mind.

 

I'm on track for studding and slamming that new head on this weekend. My truck has only been down two weeks, bit it seems a lot more!

 

Is there a benefit to milling the rockers over the valve covers?

 

Yes. ARP engineers their studs for full engagement in the block. Of you don't mill the stands there is almost 1/4" less thread engagement and the strength would be compromized as well as a change in the torque specs.

 

 

Nice job! A milling machine would be a cool toy to have.

 

I wish I had a milling machine at home too. This one belongs to a friend (has a machine shop).

 

Are you going to sell these? Kind of want them.

 

I meant the milling machine. The rocker stands are going on my truck.
