69 Camaro intake bolt question

[KevinW]

So doing some searching while building my 327 and came across some posts about shouldered intake bolts under the lift hooks. I always wondered where those went. I must not have paid close attention to that detail when taking engines apart.

So I put the correct bolts under the lift brackets, but just to be sure... Do the thin spark towers also get those shouldered bolts? Or stick with the regular unshouldered bolts for the towers? Thx
