Chuck says, "this is something that should be checked on all FE's".

I guess you mean all SHELBY blocks. The 'REAL' FE's do not have this problem, there is 'nothing to check'.
EDIT: I run a Canton road race pan and windage tray on my original FE, which I built myself. There are NO leaks, period, dry as a bone on the bottom of the motor!

Personally, if I paid the BIG BUCKS for a Shelby block I'd be mad as hell. Shelby KNOWS it is a design flaw and has taken steps to correct the problem with FUTURE blocks.

Is there any warranty or machine shop expense reimbursement for the old blocks?
