Had my 90 928 GT de-carboned at a local Porsche shop. They used a contraption that bead blasted with walnut hulls thru the plug holes.
The local Porsche dealer uses some kind of solvent thing. But when they did my Boxster S they didn't change the oil afterwards and it spun a rod bearing within a couple of weeks.
