I've been using Castrol 5W-40 which is LL-98 i believe, haven't had any issues with ticking/ill effects.
I think 10w60 is overkill for a street s52 engine, i know you guys run it in your race engines, but i don't think it's the best advice to be giving people unless they are heavily tracking their car.
