Default Block ID help

Ok, I have a 305. it's casting # is 14088551.

The ID # on the stamping pad in front of the pass cyl head is V0611DDS
the partial vin under the ID# is 2G1252588.

The date code on driv side rear bell housing flange is E206

It also has GM5.0LG near the date code.

From what I can tell it is a 305, cast May 20,1986.

What is confusing me is that the DDS suffix says it is an 83 4bbl from a Pontiac. It does have a 1 piece rear main so it cant be an 83 right? It also does not have any castings fore factory roller cam so it must be an 86. (86 = first year fore 1 piece main and only year 1 piece rear main without roller cam)

Any help is appreciated.
