Valve spring installed height

What is the most Installed height that you guys have gotten with the valves that mike supplies?
-Thanks, Jeremy

I bought some dual springs from Mike. I am putting them in at 1.595 since that is where my retainer and 0.060 thick locators (on the aluminum head) put me. Around 1.600 should be fine. Always check for coil bind and retainer to guide/seal clearance.

Thanks Dan. I was figuring around 1.600".Its good to get confirmation. I may use longer valves for more installed height. I'm not worried about the stock valve train geometry since I'm not using stock rockers.
