As promised here are some pictures I took last night, one confirming roller cam
the other a stamping of NOV with an open end wrench. This mark is on both the head as well as the block.
The LS springs not sure where those came from.
As far as the paint not matching, it seems as if the previous owner only did have a paint job, the entire back side is black, were as the front is all blue.

I also did some google foo this morning and came across this on motor tech
block # 10243880...350...95-00...2 or 4...Vortec truck, Gen.I crate motors and "ZZ4", roller cam, one piece rear seal

12558062...98......350..........L31 Vortec, truck, 64cc chambers, 1.94/1.5, 170cc intake port

Since My block has the slot for the full pump push rod, although it had the block off plate, I think I'm going to get a Carter fuel pump P7040 to get the psi for the Edelbrock 1406 (read a post from on here from 2016)

I appreciate all the responses and guidance, Im off tomorrow so I will be able to do more investigating
