    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.

    That area is tight especially with the 1" set back of the DSE subframe. I am using the stock valve covers and had to modify the coil bracket on # 7 because the booster was interfering. And that is with a 7" booster a bought in anticipation of this problem. I am also using aftermarket coils/bracketry that may be different than stock...

Same issue as you, the 2 piece LS covers do fit. However, you can’t install one of the bolts. It would require you to remove the booster to install it making the set-up not able to be serviced. I resorted back to normal OEM covers and no mods required. I ended up sending my Holley covers back regardless because the baffles were poorly secured.
