how much do you machine off for head studs

[Big Deezul]

I realize you have to machine the pedestal to clear the valve cover..can anyone tell me how much needs to be taken off. I found one post that said .20x1.1 inches...can anyone verify?

It isn't going to change stud to valve cover clearance...

its not the stud that hits the valve cover it is the nut. the nut that goes on the stud is much taller than the stock bolts head, so .200" needs to be taken off to get the nut sunk down enough to not hit the valve cover. the distance in to the pedestal isn't as crucial as taking the height off. you just need to take enough off to clear the washer.

You can grind the nubs off the inside of the valve cover and they will fit. Thats what I did.

That will not work with the new style arp's.
