[TR] plug gap for platinum plugs

[Eric Butschek]

 '78 Spitfire 1500 with original Lucas electronic ignition.

I bought a set of Platinum plugs, NGK BPR5EGP. The box says Don't
adjust the gap, as you might damage the little Platinum tip. The new
ones are gapped at .035  My Haynes manual says .025

Do I:

1. Run them at .035

2. carefully adjust to .025

3. take 'em back and get regular plugs?

Thanks.
