Power brake booster

Today I ordered the shims to raise motor 3/16" from Aimes. I notice my 11" brake booster is very close to my valve covers. I'm thinking going to a 9" booster. This is a 66 GTO front disc dual master cyl. Does anyone have a part number for what works best? And the best vendor where to purchase.
