Ignore previous review, these are the correct head bolts and were already installed from the factory in my 2008 Impala. (Picture enplanes why.)Product worked great. True, it does come with 8 bolts (not 6 bolts as the previous reviewer noted) that all have the same size head, but also included in the box is a note explaining this is by design for increased strength.So long as you use the new style lower intake gaskets that FelPro and many others sell (yup, it’s the lower intake gasket where these matter, not the heads or head gaskets) they will allow for the larger diameter bolt head with a small dip, or cutout near the outer head bolts on the intake side of the head (see pic) as opposed to the metal gasket support structure being straight across on the upper edge. This is probably only a factor if you are trying to use the cheapest parts you can to get by, but in that case you probably are not replacing the head bolts anyway…My application was a GM 2008 (impala) 3.5L motor.Hope this helps someone!

Bolt set had wrong bolts in it. Should have been 4 with a 15mm head and 2 with a 13mm head, opened box and all were 15mm size
