Interesting.... I used the extended coverage heads of tyco's that cover 18x18 so I could clear the doors (but not really because they're 12" below the ceiling when open) but I felt I shouldn't ask unless I couldn't and they'll do just fine with the doors closed anyway. I liked that analogy as well.
Tom FWIW-My living room has a '64 502" stroked 318 (bored 90 over and a 4" crank) partially disassembled (roller rockers coming) and a '93 Harley but it's got blazemaster and residential sidewalls! Wish I had a garage. Tom: Our AHJ's allow us to ignore door shadow. If they didn't we'd have to start installing heads under the doors, like 13. I really like Rolland's, "A living room with a car in it" It immediately reminded me of all the Choppers I've seen stripped down in certain living rooms, awaiting parts or ambition.
