Valvetrain Geometry

[OldRedFord]

I set up to check my valvetrain geometry this afternoon.

I am using the factory stamped steel rockers.

Wondered what you all thought.

Intake



Exhaust



Valve spring with lifter on the nose of the cam.




I used a factory push rod and a solid lifter. I had wondered if the factory push rods would be short with a bigger then stock cam, but didn't mill the heads or the block deck any.

It's hard to tell from the picture, but the pushrod looks to be slightly on the long side. A tiny portion of that will go away with lifter preload (assuming that you have a hydraulic camshaft).

Looks like the valve isn't rotating as it should be either...

I will be using a hydraulic camshaft. I also put the head on the wrong side if that makes any difference.
