I run my RP with tappets set to 6thou inlet and eight thou exhaust. Yes, the tappets can be heard, but it goes well. I have always preferred to have the tappets generous rather than too tight.
I recall, in my rallying youth, that the works Ford Kent engines always sounded positively clattery, as the exhaust tappets were set to give a constant vacuum reading for each cylinder, and i understand that they could be as wide as 25 thou, but they didn't half go well!
