Think you misunderstood, that exactly what they were built for... Stock covers but running taller roller rockers underneath. I too have a full size booster and have the same clearance issues. These are a $25 fix to solve that issue
Are those installed in your picture above? So how much room do you have now between the booster and valve covers? Yea, I was thinking those gaskets in the pic was those metal pieces that raise the cover up higher, but those are thick gaskets... got it brother!! Semper Fi Devil!
