Classic/Antique Car Repair: Big block valve covers, serch, e bay

Question
While rebuilding the big block in my 65 SS Impala,I decided to dress the engine up a bit. Do they make a valve cover taller then 2 1/2 inches but shorter then the tall ones(3 1/2 inches)? I really didnt want to change the PB booster.
               Thanks so much,
                Dave D.
