1KZ / 1KZ-TE / 1KZN 3.0 cylinder head 4Runner Dyna Hiace Hilux Land Cruiser Surf Replacement For OEM Part # 6.
Yes, AMC do cylinder heads for the 1KZs. I use them all the time as they are good quality and made out of pure aluminium ingot. Unlike the genuine Toyota ones which are made in China and are made out of recycled material. They are crap, the genuine Toyota cylinder head that is. You can get the complete AMC head for about $1,385 from SMS Diesel Spares including the cam. The only thing it doesn't come with is the inlet and exhaust manifold studs, the gasket and the head bolts. You will need a set of good stud removers to get the studs out of the old cylinder head.
