Have the block from my discovery up for sale. Has around 160k miles. Make me an offer. I have the heads too but was planning on keeping them as back ups but if you need them we can make a deal.
I also have everything from a 2002 Bosch 4.6 engine besides the block and heads. Motor had around 55k miles. Also have the torque convertor for this. Let me know if you need anything and I'll see if I have it.
