Bought some SS shorty headers for my stroked 408w build. The headers came with bolts but they were just to long. Found these and they worked great and got the headers tight.

These fit perfectly and were exactly what I needed to mount my Hedman headers!

product shown were 6pt, ones I received were 12pt. Can't use an open end wrench on a 12pt.
