There are about five postings on ebay claiming GT heads (or not in some cases) with a casting number of C8AE-H. My books tell me that true GT heads are for tht year are C8OE-A or C8OE-B. What isa being sold are standard heads. The confusion is that some have the correct 14 hole pattern for mustangs etc. Was any exhaust manifold for a 390 found on a mustang and several other cars drilled for this pattern whether it was a true GT head?
