Keep working with your repairing dealer's Service Manager / Director to learn of the repair method authorized by FMC. It will most likely go in one of two directions.
1. Replacement of a Short Block", (includes: block, pistons, con-rods, crankshaft assembled with all new bearings.). The original cylinder heads are re-used. But with your catostropic failure, the cams are most likely damaged/scored due to oil contamination and starvation.
2. Replacement of a "Long Block" (includes everything from oil pan to coil covers, so to speak.). This is basically a complete new engine assembly that only requires the transfer of manifolds and engine accessories, starter, A/C Compressor and Alternator, etc.
In general, warrantable repairs made by vehicle manufacturers will lean forward the method that requires the least amount of Technican labor to complete the repairs.
Insofar as your question regarding the engine ID pad location, I can tell you that during my Kooks header install, I came across a machined and etched pad under the L/Side, (Drivers Side), exhaust manifold. There is also a small machined and etched pad on the front edge of the engine valley bridge. (This one has casting date info.)
In the past, Ford has also been known for tagging engine ID info on the lower side of the block skirts and rear of block locations.
This is an interesting topic though, so please post up your findings on the correct location of the ID pad, and how we can de-code this important information.

PS: IIRC, Ford does not "VIN Code" every engine block, and in the early days would only VIN Code performance engine blocks, (e.g. CJ, SCJ, Boss 2's and 9's, 427 CID engines, etc.).
