Checking valve spring heights.

Thank you for the information.

Thank you espically for the above graph. That has a TON of good info I was looking for, (such as the spring pressure at height info).

But I think coil bind will be a problem.

1.560 was our shortest height.

Coil bind is at 1.100

That puts us at .460

Our valve lift on the exhaust is .466.

That's no bueno.

I'm pretty happy with where the intake height came out. One .015 shim on one spring and they are all within spitting distance in my opinion.

Thank you again for all the info. That chart is great. Thanks. Eric

You're welcome.
Have you actually measured at the valve/retainer with it all mocked up?
I bet you don't have .466 at the valve.
The rocker geometry is always off , the rockers aren't ratio accurate/correct, they are less...and then the push rod moving outward due to the 59 degree lifter angle. Lol I bet you have the .050 before coil bind min necessary.
