I am about to be installing a set of AFR 165 heads on my car. My problem is what valve covers do I use. I am running a cobra intake. A lot of the aftermarket valve covers say that you need a one inch intake spacer to clear the tall valve covers. I know that some people use 87 to 93 valve covers and do a little grinding on them. Can I do the same thing with stock valve covers on my 95?
