Valve Spring Installed Height

[kdml]

I'm doing some head work on my '65 401.  I noticed in the service manual that it lists two installed heights for springs.  One for outer spring (1.600") and one for inner spring (1.690").  I understand how to measure installed height for the outer spring (spring seat to underside of retainer where the spring touches); however, I want to confirm when checking the inner spring installed height what part of the retainer do I measure to.   Common sense tells me the measurement is from the inner spring seat to the step on the retainer the inner spring touches.  Is this correct?

 

Also, I understand I will need to shim the outer spring to get to the correct installed height.  I assume I need to shim the inner spring as well to achieve the correct installed height - correct?

 

Thanks

You are correct Doug in all your assumptions.
