This weekend I'm going to start on my second version of my single intake opening valve system with solid lifters. I built a very simple system that holds four of the intake lifters in place with no rocker arms on them, this keeps them from popping out under hydraulic oil pressure. So now I have a single intake valve per-cylinder to promote swirl for ultra lean burn operation. This will also help with engine delt p by increasing intake boost pressure from a more restrictive valve area.

The only downside to this is the fact when I want full maximum performance I will have to pull the valve cover and remove the lifter holders, and put the rockers back on. I will also be experimenting with the exhaust valves also.
