Any advice appreciated

If you do low mileages and tend not to drive for prolonged periods at high speed, chances are it's not a problem. If, like me, your car is going to do 20k a year then you'll want an additive or an unleaded head.

Additives - at least here - are fairly cheap; unleaded heads - even getting a head converted - is not that expensive (I was quoted 150quid for having an A-series head reconditioned and converted to unleaded by a local engine shop). You may be lucky, and run for years on unleaded without a problem. Or you may be unlucky and have valve seat recession very quickly.

It depends on your driving style, how much you drive, and how lucky you are.

91 Octane - that's low. But if it's just a fun car for low use - it will be fine. Just keep an eye on the exhaust valve clearances - and set them at 15 thou to make sure a gap is maintained even at high temperatures. If the gaps start closing up - that's when to start looking for another head.
