Hi Dave

Haven't done it myself, but I am sure they say the minimum gap is something like 0.35 mm, so I think you are ok (that spec is on the 148cc)

I don't normally go beyond the cylinder head of briggs since they are so cheap to pick up a whole other running engine (though I will have to rebuild a Quantum 50 eventually due to sentimental reasons)
