The original poster mentioned using a spacer. What size spacer do you plan to use (that will affect your decision on brace). I have the same issue. I have the Edelbrock intake with 3/8" spacer, taller valve covers and the Cobra R hood. The stock brace won't fit. I talked to a rep at Maximum Motorsport and he suggested that I may need to get the strut tower brace used for the 351 engine because it is taller. You may want to give them a call. From what I've noticed with my brace clearing the intake isn't the problem - the problem is clearing the TB.
For those that replied - are any of you using an intake spacer and taller valve covers. If yes, then the braces you suggest are probably ok. If no then I don't think those braces will help the poster.
Oh by the way, if you put on an intake spacer, you may need a new hood too?
Peace
