Default Engine balancing??? 6.0

I'm trying to get parts together so i can get the rotating assembly balanced at the machine shop, and I need to buy a flywheel and harmonic balancer. however I noticed that there is an internal and external engine balanced style of flywheel. and internal external and neutral harmonic balancer
it's the it's the crankshaft from an 01 silverado 2500HD
so my question is what do I need?
and would u recommend an 18 lb flywheel and underdrive harmonic, because thats what i was planning on...
But i don't know if it's internal or extrenally balanced?
thanks in advance for your help.
Stuart.

LS Cranks are internally balanced.

This is what you need to know to figure your Bob Weight

Connecting rod big end ____ grams
Connecting rod big end ____ grams
upper bearing insert ____ grams
lower bearing insert ____ grams

piston ____ grams
wrist pin ____ grams
Locks ____ grams
Top Ring ____ grams
Second Ring ____ grams
Oil Ring ____ grams
Support ring ____ grams
Connecting rod small end ____ grams
oil 8 grams

Total is bob weight

Its been a while since I've balanced a crank, but don't you want to double up the bearing weights as well?
