Fluid routing

Routing the hydraulic fluid for the valve actuators through the block is taking a lot longer than I expected. I wanted to keep the solenoids out of the valley and away from the heat and vibration. This would allow me to service/upgrade the solenoids without tearing into the engine as well. The downside is that instead of one pressure and return line going into the block, I have to have a line for each intake/exhaust valve going into the block. I spent a few days trying to come up with an efficient way of doing this and came up with a bolt on piece that looked similar to the valve body in an automatic transmission. I decided to ditch this because it bolted on. Expansion, contraction, and flexing would affect the mating surfaces and numerous seals and gaskets would be required. This introduces to many opportunities for leaks in the system. Any failure in this system would be catastrophic so I want to eliminate as many possible ways for it to fail as I can. This will also be cheaper since I will not need a separate piece machined, o-rings, gaskets, bolts and washers. Judging from the many designs on paper, I will most likely have to play around with the actuator locations in order to have these hydraulic fluid passages machinable. Looks like stock pushrods might not be possible. Here are a few screenshots of the block. I have not done much since the last post. I have spent most of my time drawing different possible solutions on paper.
