Explain that.
This.

You don't drop pulleys until your 100% knock free on the current one.

IIRC you only had the car for a month or 2 why are so anxious to drop pulleys? Solve your knock issue and then drop pulleys. Or risk it and look forward to engine trouble.

Oh and while your at it get rid of that 180tstat until your tuned for it.
