You will need to have the stand milled off for Clearance.
One other thing I would like to mention is do not use the cap spacers on the bolts to ride directly on the Aluminum rocker . Place hardened shims on the shafts between the aluminum rockers where they ride against the bolt spacers .
You may have to mill the rockers and the spacers provided with the rockers to center the roller on the valve tip to make room for hardened shims. Hardened shims should be used between all the steel spacers and aluminum rockers. Otherwise the bolt spacer will wear into the aluminum
When you buy the bolt spacers new they are all the same width, 4 wide 6 short. Then they are ground to fit the application for fitment. Every head is different. Watch your pushrod location where they travel through the head.
