There should be little or no issues putting the engine and head together, however the first step is most important. Ensure that the engine is set with the Piston number 1 at top dead center ( check the timing mark on the crank pulley or remove the pulley and there should be a little arrow and grove in the inner timing cover line up or ensure that the woodruff key is at 12 o clock. For the head spin the cam shaft bolt until the mark on the cam is centered on the pointer ( both marks can be hard to see the cam mark is a small O on the rim of the cam before the timing belt groves).As for the fuel pump you should just have to remove the two bolts from the cover and install the pump. What kind of oil pan did the MGTD have a front sump or a rear sump ? Check with any of the MG boards for more info this swap is not a rare item. There is a way to  find the dip stick hole, look for the FP that is cast into the block you will have to remove the PCV and hose off of the crank case breather assembly .And then look straight  down ,that's where  the front hole is . To move the dip stick around,  remove the oil pan and than use a bolt that is smaller than hole to drive out the plug, note do not use a pin punch or you will bend the plug.

Thanks for the responses.  The engine has a front sump but the block I have doesn't have a front dip stick plug or hole.  It is a later model block.  It also does not have a cutout for the mechanical fuel pump which is why i assume i will need an electric one.  I will try the member map and Racer Walsh to see if i find someone here in Jacksonville.
