Parts update:
Headers - Bought these today..
http://www.schoenfeldheaders.com/LS1-TRUCK.htm $300ish shipped.. (bought from a speedshop somewhat local, they are going to be factory shipped to me)
Flexplate - Bought GM part number 12621399, flexplate with spacer and bolts. $74 shipped. Found the flexplate several places, including sdparts.com, but ordered from crate engine depot. Ordered from there because their part number shows the flexplate as a kit, where some places are not selling it as such.
MSD 6010 - Ordered from Summit.
TransDapt Motor mounts, part # 4572. Ordered from Summit.
Also bought gaskets as needed from Summit.
Have the shop cleared for I can get the pickup in tomorrow to get the ready of the goodies out of the way.
I have also heard of people having issues with the stock oil pan clearing the front crossmember, can anybody confirm/deny?
