Hi all, I am planning to fit external wooden door and frame, on newly built porch.
I have never fitted an external door frame before, so any tips would appreciated.
Do I fit a wooden header to cover cavity at top of frame

What are the dimensions of your opening?
What are the dimensions of your door frame?
Is it timber or plastic?

As a general rule when you fit a door frame wether it be timber or plastic, it is standard practice to allow 10mm clearance (5mm all around sides, top & bottom) to allow for setting the frame squarely into the opening.
You then use either some thin timber wedges or those plastic packers which upvc window fitters use for taking up the difference between the frame and brickwork at the points where you have drilled for your fixings.
When drilling for your fixings you need only fix the jambs (sides) of your frame not the top or bottom.
Once you are happy with the fixings and that the frame is level/plumb, you can then use expanding P.U foam to fill in the gaps around the frame to get a pretty good draught proof fit. (Once the foam has set it provides additional sturdyness to the overall fit)
Finally, you can then fit a cover bead around the frame on both inside and out to finish off and hide the foam joint, usually a quadrant type bead is used on a timber frame.
Are you intending to have the porch rendered? If so, the fitting of a cover bead may not be necessary, either at all or until the render has been applied.
As far as a header piece goes, you may well need to fit one, but will soon determine what you need once the frame is in place.
Tip: From your picture it looks like you will be drilling into block, so when you do the drilling don't use the hammer action on your drill otherwise you could end up with the blockwork breaking away. Assuming that is a soft type block. (you'll soon know when you start drilling)
