I have what is called a long cam version of the KAD head, unlike the current, short cam version which KAD now markets (due to competition from the now deceased Jack Knight 16v conversion as it was an easier mini fit).
In fact the head is apparently KAD head number 5. The early ones had difference in a few areas, such as the way the oil flows back to the block (from the back on mine via a pipe that bolts to where the fuel pump used to go) through to the use of EN40B steel Imp followers. The later heads use the wider BDA followers.
The exhaust manifold is a stainless 4 into 2 into 1, with a lambda plug which plumbs into a bespoke maniflow stainless exhaust. I need this plug on the manifold to use with the Innovate LM-1 data logger/Wide Band AFR sensor which is handy for setting up the car without access to rolling road.
The first cams I had fitted were the KAD2 fast road ones. I now have the L14 ones which are about 286 duration. The codes on the cams generally match the profiles of BDA engines as apparently they use the same profiles. Ideally I would have gone for the L1/BD3 combination which is a slightly softer variant of the L14/L14 variety.
