My personal inclination would be to hunt down some cheap 20W/50 - Halfords have normally got something for 'classic' cars. It does not need to be anything fancy.
Logically I can't see any reason whatsoever not to use a 10W/40; it's probably a better choice - I simply never have, having a lifetime's satisfactory experience of 20W/50.
With a clean engine and full-flow filter a detergent oil is no problem at all, though as Reckless counsels, on a older engine it's possible some muck may be dislodged.
