I need to know what the thread size is for the bolt holes on the end of the heads in an LS1

built a custom bracket for something, just need to secure it to the head in one of the bolt holes

i literally just built a bracket for my pcv catch can last week. I'm pretty sure (95%) the bolts were M10's. i bought them at home depot so they are pretty common. A M10 is 1cm for a frame of refernce.
if thats not it let me know, i can dig up the reciept if i have to.
