those ebay kits are for the most part, cheap Chinese shit that I wouldn't touch with a really long pole. There are some half decent kits out there as well, but they are not super cheap. I would just order a OEM headgasket, Good quality sealsn (cams, crank, oil pump, front balance shaft, crank seal), and valve cover gaskets (felpro or KP or OEM), timing belt/water pump kit (gates/mitsu/GMB components/pump), pistons rings (NPR are good) , main and rod bearings (KING bearings are good) all separately. I would also only recommend using OEM timing hydraulic tensioner and also OEM oil pump/front cover and rear main seal.
