OK. the big day aproaches and the fuel is in...

i would remove the plugs, place one of them in a plugcap and rest it on the top of the engine. then crank it over untill oil pressure lamp goes out
whilst observeing spark plug for sparks if the oil lamp goes out and the plug sparks then refit the plugs put the leads on (in the correct order LOL)
cross your fingers and just go for it, recording every second of it for prosterity and when i fires you'll crap yourself, then won't be
able to stop grinning at the life you've given to the beast fron the garage
good luck mate

AWwwwWWWWW
Getting electric shocks from testing for a spark like rich says ^^^^ is part of the fun
ESPECIALLY if you dont put a bung in the plug hole so you have petrol being sprayed at you whilst youre holding a sparking plug in your hand winceing
at the electirc shocks youre getting
Ahhhhhh brings back such happy memories

Why not just see if it fires when you have oil pressure? Test for spark IF it doesn't start?

Turns over but did not start
can smell fuel fumes from exahust so suspect there is no spark.
will remove plugs and test one of them on monday, time to bath my little girl now so no more noise tonight.
edit - ok where do I start. what should I check to help locate the problem.

get an old (known working) spark plug
pull one of the ht leads off one of the plugs in the block (leaving the plug in for safety)
insert the old plug in the ht lead
touch the bent bottom bit of the plug to the cylinder head/rocker cover
keep a very close eye on the gap of the spark plug while tunring the engine over
you should be able to see a spark jumping the gap.
you WILL probably get a shock which is always a surprise (but is a bit of a laugh too IMO)
