Will the new E-series heads might fit on the A12 engine? Note that the 1982 E15 engine design is based on the A15 engine:
* Same bore & stroke * Same bore pitch (82.5mm - 90mm - 82.5mm) * Lighter casting * Similar head gasket * E15 is overall shorter to fit transverse applications (FWD)
E15 Crossflow head with semi-spherical chambers improves on A15: HP and torque are both up 3%
The E15 uses a jackshaft "in the area where the camshaft is mounted on the A-series engine" to drive the fuel pump and oil pump (the distributor is driven off the front of the cam).
