I've used Toyota's own gasket kit in the past Rob, don't think it has a distributor seal but it's got a lot of other ones:
This kit covers most, if not all, renewable gaskets on the 4EFTE. The materials, specifcations and thicknesses changed over the model years but each kit supercedes the previous version.
Part number : started out as 04111-11101 and ended up as 04111-11104
Price : £122.33 inc vat
