Bellow are pictures that Paul Burke just sent me of the B35 head he has prepared for my engine. This is PhD machine work here, over $50K worth of machinery is required to accomplish this -
The surface you see here has been measured by a $3,000+ Profilometer. It is a 16 RA. Yes, a 16. A stock head from the factory is between 45-55 RA. To review why the RA is so important to a FI engine with a MLS head gasket, look here - Clicky
Look at the valve seats. The multi angles were machine cut, NOT ground with stones. So are the valves.
Here is a close up -
Here is a pic of the adjustable cam sprocket -
The side you are looking at receives the four bolts. They pass through a second plate that has the actual sprocket teeth and that plate has slots for the bolt holes. The dots you see at the bottom are for adjusting the cam. Each dot is 2 degrees advanced one way or retarded the other. The reference dot is on the moving sprocket plate and the other timing marks are on the fixed cover plate. So the cam sprocket is sandwiched between the cam mounting plate and the front plate. Just loosen the four bolt and the sprocket can be adjusted.
Now here is quite a teaser -
This is a mock up of a roller rocker for the M30. How cool is that?
