Anyone know the size of the harmonic balance bolt on a Chevrolet Silverado 4.8 because I'm removing and replacing the valve stem seals?

Got this posted on the wrong forum section bud.

But to answer your question, it should be the same as the 5.3 (16 MM x 2.0)

Haven't heard anything about them. Used them on the Saab when I did the DOD delete and reconned the heads. No problems here.
