Still think its a foolish move not doing the manifold gaskets..... 
Aye... the rockers and cambelt are fine to do in situ... I would have done the manifolds while out though 
Yeah, you too James. And just when would I have put the engine in then?
Fin Fin Fin...
Nobody is getting at you mate.
All I said, is, that
if it was me I would have done the manifold gaskets. If other issues such as time constraints, other commitments or anything else meant you didn't want to or weren't in a position to do them - that's entirely your choice, and I respect you've got your reasons.
In fairness to Mark, he didn't suggest changing the gaskets because they are there (to quote your above post). He suggested changing them because on a second hand engine that you haven't heard running (presumption) - you cannot guarantee they don't blow - and as we all know, those particular gaskets are a lot easier to do properly with the engine out rather than in, so potentially it could save you a lot of time and bother.
Looking at it from your side of the fence... if a stud had of snapped on you, then you could have been set back by even longer, so I can also see some advantages in leaving the gaskets be.
Bottom line, this section of the forum is for general chat and sharing of opinions - which will never always be the same. I'm pretty confident in that 99.9% of anything said or suggested here is intented to be nothing but helpful and constructive.
That's certainly all I ever try to do. So my apologies if it came across any differently.
