Early Olds Valve Spring Height?

Could anyone tell me what the OEM valve spring installed height is on the 1955 (number 8) heads is? I have went thru 56 heads before and have those handy but I'm damn sure 55 are shorter by over .05. I went through all the specs of various springs and have what I'm looking for down to approx installed height. Still haven't found my dial to just measure myself but would like to order and have them for next week. I would also like to know where the hell that dial mic is before they get here so I can figure any shimming. So, if anyone would like to clean a shop.....!
Any way I'd would greatly appreciate those specs! I'm going to go clean shop now and make it harder to find every other tool, does that happen to anyone else?
Thanks in advance!
Mike

Thank you sir...I Couldn't have had a more knowledgable guy respond than you!!! I'll have to PM you when I get everything together, I'm pretty sure you'll want to see this.
Thanks again
