Big Block Chevy Head Bolt Markings
Does anyone know which head bolts markings are correct for 60's-early 70's Big Block Chevy engines. I have a customer looking for a set of head bolts for a 67 Camaro he is putting together and I am not sure which bolts are correct. I have looked at used sets I have bagged up that I have pulled off 1970 and earlier BBCs and they look to have a mixture of the markings of the NOS bolts he is looking at(pictured below). Are any or all of these marking correct?
Thanks, Jason [img]<<GRAEMLIN_URL>>/youguysrock.gif[/img]

Re: Big Block Chevy Head Bolt Markings
Jason, the "M" on the head is correct for those years and the most desireable, at least that's what I've learned from my experience.

Re: Big Block Chevy Head Bolt Markings
Kurt,
Thanks for the reply. I wonder why the M marked one is most desirable? Mot sets I have taken off of actual engines have the X/+ marking but a variety of symbols. Thanks again, Jason
