Simon,
just re-reading your post, the oil pressure should go off the scale when cold. If it does not do this, your friend should consider investigating. Numerous potential causes - oil vane/s incorrectly orientated, vane springs broken/damaged, oil pump cover and or body very badly scored, pressure relief valve not fully seated, incorrect rear cam bearing fitted etc.
