I believe, at the time VB was selling Kent cam kits for both GT6 and
Spitfire, they offered a range of kits for the Spitfire, but only one
grind for the GT6, Kent's TH2.

Quite right. Specs for what I believe is the correct grind are:
Cam Lift: 6.62mm (0.260")
Lift at Valve: (0.390") (1.50:1 Rocker Ratio)
295 deg. duration
Timing: 39/76/76/39
Inlet Timing at full lift: 108 deg.
Clearance: 0.36mm (0.014") Inlet, 0.46mm (0.018") Exhaust
Cheers.
