Clean the intercooler, only once, then install an effective oil separator, then it will keep it clean for miles and miles to come.
Change the SC oil, on the Whipple manual it says every 100k miles, which I think it's around the same for the Heaton (stock SC), but it also depends on the size of pulleys you have, if it's not stock, it raises the ratio consecutively the RPM's, I'd double check the specs here to be certain of the intervals between changes.
