M Code 440

I did a quick search and didn't find my answers. First off, what would be the intake manifold bolts? Just like a typical 440 of same vintage, but, did they all have the "TR" marking? Second, the valve cover bolts. I know in some years they used a short stud with a nut in the lower corners. Maybe that was early 60's? Were they all the normal bolts for 69? Getting down to the finer points on this engine and want it correct as possible. Thanks for any and all help!!
