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
