Real racers/mechanics don’t purchase from pics

I’ve bought cometic gaskets for years. They are the best. The rubber coating helps save time on future builds. No scraping off fiber residue. I’ve always received all gaskets in the kit. At the Bottom of the written description theirs a list of gaskets included in the kit. Pictures are just for advertising and are most likely not even pics of parts for your model.

Not happy

I bought this gasket set expecting to get the valve stem seals and they were not in the package. Should not show them in the picture in the description if they are not going to come in the kit.

The base gasket doesn’t fit and the head gasket wholes are not close to correct spent 44$ on this and 4 off the gaskets dont fit wouldn’t recommend.

Okay

I bought this because i read the comments, there were only a couple that said they were missing gaskets, Well when I ordered it,
sure enough I was missing the head gasket.
