Bruce, When I acquired my '63 Volvo 1800S, it would instantly pop any fuse placed into one of the two (yes, two) main fuse slots for non-headlight accessories. I ultimately had to dismount the interior light fixtures as part of my search&destroy operation. I found the hot wire to one of the two rear seat lamp fixtures was clamped underneath the metal body of the fixture, and it had bitten through the insulation to provide a hot-to-ground short. I don't know how long the P.O. had tolerated that, and it took me a while to debug. Your battery drain problem post-head-gasket work sounds like it could well be a wiring harness issue precipitated by a stray screwdriver or mis-clamped fitting. You can possibly pull the wires from behind the fuse block to separate the loads and identify w/o having to get to each of the loads at the point of use. In fact, if it's the harness that's impaired, you won't have any joy from measuring at the load, as that wouldn't be the problem.
Good luck with this. And quoting your loads in "volts" of drain only confuses the matter. I'm assuming you mean "Amps" and 8 amps is quite a static load. Sort of like a 100W light bulb on a 12V system. The problem child ought to be visible, smoky, hot, or at least smelly.
