Hi Stephen
Make sure you have petrol,
oil and coolant in all the right spots
Then crank her
After it fires and you eventually get an idle you hop around from one foot to the other whooping like the village idiot (who else would build a cobra?)
A few moments on you notice steam/smoke and shut her down rapidly with a concerned look on your face only realize that it was just some stray material on the headers.
You stand back, put your hands on your hips and grin with a starry eyed expression for the next 10 mins.
thats about it.
