Reply to "CHI 3v 225 Heads Guide Plates"

There are adjustable, i.e., two piece guide plates.

I have them for my AFR Windsor heads. They actually aren't easy to use since you need to check the alignment at full lift. The one piece are much easier to use and align properly.

You do need to get this right since you will bend the pushrods and/or damage the rocker arms.

 

Because of these issues you are better off using heads that are meant to use the original Ford valve train components.

 

I would go with what CHI says to do and if that doesn't work then the most likely scenario is the heads are not machined accurately and see if they will honor replacing them under warranty? This may not be able to be something that you can correct if the geometry is off that much from the manufacturer.

The location of the studs on these heads has also be controversial as far as I am concerned. It's the angle of the boring and threading of the base that can be an issue?
