Valve cover clearance

[84bigblockswb]

Howdy from Texas--- Been a member on the board for a while but this is first post. Been a reader mostly and have had a few questions but usually I look around a little and someone has asked and answered already. Anyway, in the process of a 427bb swap into an 84 shorty. Im using Harland Sharp rocker arms on cast iron heads so i've got to use tall valve covers. The truck has power brakes and was concerned about tall covers hitting the brake booster. Wondering if they will clear, and if not, what the cure was. Thanks in advance!! John
