Did GM switch original 10mm exhaust manifold size for LS1?
Just got new bolts today for my headers. The heads are not 10mm like the stock ones. They fit a 1/2 socket perfectly. The part # is 11518860 on these bolts but when I call GM they dont have that part # listed for the Camaro. This part # is listed for a truck. I did a search and there is something about switching the bolts but the info isnt adding up. Anyone have any info?

I know for a fact that the later model LS vehicles went to a 13mm head bolt as opposed to the older 10mm head bolt. You have the 13mm head bolts which is why they fit in the 1/2" socket. They are perfectly fine to use.
