I've completed my investigations into the heater plumbing, and concluded that those who said "bottom hose" were entirely correct.
I've also managed to find the steel pipe which is intended to carry water under the sump on this engine (removed for belt replacement/ engine removal nearly a year ago) which will ease the pipe routing considerably. I also spent most of today removing my original effort of silicon hoses and joiners, and replacing it with a veritable artwork constructed entirely from stainless steel pipes which I tig welded together, to make room for the extra pipe. So, thanks to Robert, John W, Gary and the guys at Haynes for their advice and input. Now....I wonder if the oil-->water cooler is also supposed to go on the heater loop....
