I apologize for not taking many pictures lately but I have made some progress.
I completed the cylinder head, valves, valve guides, and installed the spark plug.
I cut cooling fins around and on the top of the cylinder head.
This shows the under side of the head.
As you can see the valves are not centered up and down in the head. They were raised up 0.130 from the center line to allow for more room for the spark plug socket hole. That little plug is way down in there.
Starting to come together.
Today I cut out the rocker arms and the rocker arm stand. The stand will be attached to the head by one longer head bolt. This has worked well for a previous build.
I also set the valve timing for startup and made two push rods.
I am still unsure about a fan blade for cooling. I received a nice little 2" diameter blade but even with a shroud around the blade it didn't blow much air. I have a 3 1/2" blade that does move a good amount of air but it seems a little too big and would create more issues.
I will just have to study on it for a while and maybe something will hit me.
Thanks for looking
