Thanks for the kind words.
Some time later I bought a Kent fastroad cam kit for my 2.9 12v.
Marty, who is also on here somewhere, helped me putting it in (or more the other way around

), as at the time I didn't have much experience yet working on engine internals.
To put the cam in the heads need to be taken off, so we started with removing the top of the inlet manifold.
After that the distributor and fuel rail were taken off.
And the inlet manifold off.
Removed the rocker shafts.
And both cilinder heads removed.
And lastly, the timing cover.

After one day the car was standing like this.
The next day the heads were cleaned, the valves were lapped in and the new valve springs were fitted. We also fitted the new cam but I forgot to take pictures.
The heads and the inlet fitted again.
Fuel rail, rocker shafts and distributor back on.
And after that fully back together again of course, but I again forgot to take more pictures...
