I have Chevy Silverado 2010 4.8. They said it would fit this car but it doesn't have the correct valley seal or o-rings to fit the valley. I've wanted to come here for a while to add to this review that head gaskets are junk and I repeat junk they blew out on both sides after 800 miles. I wouldn't waste your money, spend some more and get something good by investigating my mistake. don't buy cheap
