I bought some of the Holley 2 piece valve covers and went to install them but they wouldn't fit because of the brake booster. Has anyone had had this problem and if so what valve covers did you go with. If they are the style that the coils mount directly to the valve covers did you have to upgrade the coils and get a different wiring harness. Parts and pics would be appreciated. Thanks in advance, I need to order these so I can get the motor running.
