I am doing a head swap and the old gaskets were not in best of shape so I ordered a new set from Doug's.
When the UPS guy delivered them today I noticed how heavy the package was and after opening, I see not only did they send 2 gaskets but also 2 3/8" header flanges with gaskets sandwiched in between.
I guess this was only to protect the $28 gaskets or to make my own headers in future? :)
