roller rocker arm clearance with COBRA valve covers

I'm looking into upgrading my rocker arms to the Crane Energizer 1.6 full-rollers and was wondering if i will clear my valve covers. Does anyong have this combo? I dont want to buy new valve covers, and really dont want to add spacers.

will i still be safe with my press-in studs?

also, is there much difference between the Summit rockers and the Crane ones? I know the Crane Gold rockers would be overkill

the covers i have:

The only clearance issues you are going to have will be at the baffle plates so they will have to be removed. You don't have to worry about the press in studs as your stress on them is not going to increase with new rocker arms but a change in camshaft and valve springs could make them suspect.
