Wouldnt have thought so, just so that its not rattling, what the thread of the bolt is going in to is very soft so I would do them up fingure tight then maybe a 1/4 - 1/2 turn extra with tools. I think a few of us may have cracked the head cover by over-tightening!
did you have the usual oil in the plug wells?
No probs , my bonnet needs a respray too, its got small cross scratches over the middle part, il get a quote when it goes in for a front bumper respray and removal+refit! Bloody saxo drivers not looking when reversing in car parks! First and last time I take it to sarf-end!!
