Well packaged, was perfect fit. Fixed my compression and rough idle problem. Only time will tell how well it holds up.

Great price, fast shipping, unfortunately package was bent , kinking the steel ring around the cylinder, rendering it useless, won’t take any chances after planing head and labour involved, I will reorder because it looks like a well made gasket and hope it’s packaged differently next time.update-seller personally sent new gasket-amazing customer service

I specifically ordered this product: Serria 18-2946 because the picture shows it is the all metal gasket.What arrived was the correct shape/size, but it is the dark gray gasket material. I do not know if the gasket will hold up, or if there is any metal in it. Since I am on a deadline I decided to install the gasket, in a few months I will update my review.On the package for the gasket, it says:18-2946When you open it up there is another number: 1827R Head Gasket QTY: 1 PCE
