No Cylinder or Head gasket

All the gaskets for doing the crankshaft work, but the kit kit not come with the head or cylinder gasket. I missed something in the description ???? Normally a gasket kit includes ALL gaskets. No worries, it's still 2 weeks until race time and i should have checked it out sooner. Great Prices Great Service

Not complete

Expected per the description of the gasket and seal set that all gaskets and seals would be included. They are not!!!! Called Dennis Kirk and Wiseco both on this and got absolutely no help with acquiring the missing o-ring. Had to spend another 15 bucks and wait a week for the seal to get to me for assembly. Pretty lousy that they dont include a 4 dollar o-ring in the kit.
