Just a word of advice,

NEVER run a freshly build engine on fully synthetic oil. Basically if you put new rings in an engine, consider it as requiring running in. Use a fairly basic spec oil and run in on upto 3/4 full load for 3-500miles and don't labour it or sit with it at a constant throttle for any length of time.

Pop a new oil filter on when you change the oil. Usally manufacturers oil filters are way better than pattern ones like some nasty Halfords rubbish.

If you have hydraulic lifters Wynns Lifter Treatment works very well at flushing them out and is safe to leave in oil until next change.

We specialise in MG Rover stuff and do a lot of engine/transmission build work but I will admit not know so much on the Ford engine families but some techniques are true what ever you build.
