Have got two NOS heads which I hopefully can use for my stock 1,7 D-jet.
However they have an odd number "021 101 371 B" (the originals have an "Q" at the end) and also there is no ventilation tube (can be fixed) and no CHT hole (can be fixed). The valves are the same dia but the holes for the pusrod tubes are slightly smaller (guess that can be machined). What engine are theese heads originally made for and what are the issues for using them in a 1,7 D-jet? /Lars S |
