Police found £300,000 of heroin hidden in a tub under the stairs of a drug dealer's home.
Officers searched Stephen Wilkes' property in Goose Road, Chatham, on March 12.
Now the 29-year-old has been sentenced to four-and-a-half years in prison after admitting supplying heroin.
Maidstone Crown Court heard how the class A drugs had been stamped with the logo of the car manufacture Porsche.
Wilkes was later charged with possession of heroin with intent to supply and possession of cannabis.
Investigating officer Detective Constable Mark Froome, of the Kent and Essex Serious Crime Directorate, said: "This was a significant seizure of drugs that would have disrupted the drug supply network in the area.
"We will continue to target those intent on dealing in the death and misery of class A drugs and will not hesitate in putting those involved in drug supply before the courts."
