Just to say, there is such a thing as 'inaudible det', which can be just as dangerous.

Trying to help is all, and good you are happy with it now.

Doubt you'll get him to read plugs for spark knock when he won't even use a timing light, he times it by ear

Yes I'd say with cranking compression of 200+ before with this same cam, and running pump gas, there was most likely spark knock before, he was likely unaware of it. He may like how it drives since a baby cam like this would require no tuning at all for smooth operation but it'll take a while for him to find out that any detonation will come back to bite him if he drives the car enough.
