I've not had a chance to look at this yet as my spare (SD1) heads are burried in my loft somewhere
But basically I've got a 4.0 bottom end with 10 bolt head fixings.
Do I need to buy matching 10 bolt heads ?
Or is it possible to use the earlier 14 bolt type and just omit the other four bolts ?

No problem with using the 14 bolt heads, just omit the 4 bolts.
You can cut the heads off some bolts and epoxy them in place if you want to be picky.

Now I've got to thinking about which type of head gaskets to use, early or late ?
Does it matter ?
More research required on my part I think

I don't think it matters, but if you want to keep CR, the tin gaskets were used on the 14 bolt heads, or you can skim the heads for the later composite gaskets. Alternatively, if CR isn't an issue, then use your favourite supplier.
