Ginge, taking the head off is the most scary bit after all you've done so far. You read the book three times, then check it again cos you're not 100% sure... and all the time you worry if you're doing it right or not.

Make sure you have a decent breaker bar too or you won't get the head bolts off, mine's three foot long and required a half decent pull on it. Making sure the splines are nice and cosy in the head bolt is a good idea too... you don't want to smooth those bolts to the point where you have to drill them out

Looking good so far, good luck
