Edelbrock head questions

Ok, I got a few questions for you guys that have assembled your Edelbrock heads and know some measurements on them. I'm just trying to make a list of what I need for my valvetrain, and I have yet to disassemble the heads. My questions are:
1. What is the installed height of the valvesprings on these heads?
2. What is the o.a.l. (overall length) of the valves?
3. What is the max valvespring diameter without machining the heads?

Any input would help! Thanks!
