You'd really need a good cam also to compliment the head, so worth equating that into costing also mate.
If you are not chasing figures then the standard head will be fine.
There's a few options, my old fiesta for example had a standard head, a Kent cam, 4x4 cossie T3 with a .63 housing, low compression and weber management mapped holding 22psi, was rolling roaded at 255bhp with 252ft lb
It all depends what the overall result you are looking for.
A head swap at a later date is no biggy
