Fuel injected e31 head

I have an E31 modified to accept the N42 EFI Manifold on my daily driver - works well with a 60MM throttle body and Haltech ECU.

 

I drilled/tapped the head for the EFI manifold's bolt pattern (had to weld up where water passages where intersected) and carved out the injector spray holes in the ports.

Done it as well. E88, but same difference.

Blurry, but you can see the detail.

When drilling the top inner mounting holes, be careful not to go all the way through the head. There's less material there in the early heads than in the later ones.
