Tussen uitlaatpoort 3 en 4 staat het modelnummer vd kop, ws. 1000398. Maar zelfs als het een ander nummer is passen alle koppen op alle blokken en werken nog ook. *Behalve de 1000631 natuurlijk*
Eerst (laten) nakijken op scheurtjes en vlakheid (max 0,5 mm diagonaal, 0,25 mm dwars), hoe dik zijn de klepstelplaatjes, zijn alle tapeindes goed, dat soort dingen. Er valt weinig te reviseren, ze zijn goed of niet (meest goed).
Van Turbobricks:
1000160: the oldest head. Usually with big coolant passages, some have been made with small coolant passages. So called "little" head. Used with early b21 engines. The older type of cam cover fits to this, the newer does not.
1000398: Very similar to 1000160. Usually with big coolant passages, some have been made with small coolant passages. Also so called "little" head. Used with b19, b21 and b23 engines. The older type of cam cover fits to this, the newer does not.
1000530: Very similar exhaust and intake passages as on the -160 and -398 heads. Always with small coolant passages. This too is a so called "little" head. The newer type of cam cover fits to this, the older does not. The head mounted spark distributor can be used with this head. Used on b200 and b230 engines.
1000405: This is a so called "big" head. Has usually big coolant passages, but some are made with small coolant passages. Usually comes with k-jet injector holes, but some are without. The older type of cam cover fits to this, the newer does not. Used with some b23 engines. In euro version the H cam was used with this head on the volvo 242 GT with the b23e engine.
1000531: This too is a so called "big" head. Always with small coolant passages. The newer type of cam cover fits to this, the older does not. The head mounted spark distributor can be used with this head. Used on some b230 engines. This is considered to be the best std. 8v head. This head never has the k-jet holes as standard. They can be made to this head though.
