XU10J4RS head on XU7JP4 block

[Dollores]

If changes are only exhaust manifold and the cams XU10J4RS.

I see no immediate need for adjustment in the ECU map.

The change in the ECU map is mandatory when we installed the XU10J4RS intake manifold.

For full installation of XU10J4RS head at the bottom of XU7, would have to see fits the pipelines of water.

Does anyone here use XU10J4RS head on the block XU7 ???
