I am trying to swap out my valve springs and push rods.

I removed the stock spring and seat.

Here is where I am confused.

When I removed the stock seat, there is still a metal shaft around the valve stem. I am assuming this stays on.

I then put the new spring seat over this metal shaft, wigh the hat part facing upwards.

I then slid the new valve seal over the metal shaft and tapped on with a socket.

There is still ~ an 1/8" to 1/4" gap between the bottom of the valve seal and the top of the seat hat.

Is this correct, or do I have it all jacked up?

You are going to have some gap, that is perfectly normal. The seals just sit on top.

THanks for your help!

Next question - the new hardened push rods have a ball on one end and the other end is just rounded. The stock push rods have balls on both ends. Should the ball be up or down on the new hardened push rods?

The radiused tip is the rocker arm side.

The undercut is a provision to avoid a binding in the cup of the rocker arm.

BTW... not all push rods look like stock. The good ones have a 210* radius tip on one or both ends. ;)

Thanks Ed!

I am assuming that radius = the end with the ball on it.
Yup... one side is a straight and a radius, the other is under cut and radiused.

There is actually no "ball" on the end. It's a crimped/machined end on one side of the tube. ;)
