Thank you for sharing the push rod information. That is one of the items completely missing. In your build did you include a pressurized oil system?

NP john, hope it helps you! also just a heads up, the pistons do need valve relief notches to be machined so valves don't hit them at high rpm

As for the pressurized oil system....in what respect? there is no external oil res. if that is your question. if the oil pump is built well I don't believe there is any need. Please clarify if I have not answered your question.

Thanks for the reply. The plans don't show the oil gallery path after it enters the top front of the block and into lifter valley. I'm curious what you did for routing. Hopefully, this makes sense.

The majority of the oil gets fed to the top of the engine from the valley ridge to the heads. Each of the heads have a trench which guides oil to a drain tube that goes directly back through block and water jacket into oil pan. Oil doesn't pour directly into valley space just enough gathers on the lifters which drains also back to pan. Sorry if I'm not putting into written words what I'm seeing in my head, but I think that explains it!

BTW the valley ridge also routes some of the pumped oil to top of the cam
