Looking in my Crane Cams Catalog, it looks like they recommend a dual spring part# 99893, Should have about 120# closed pressure?

I have a set of Crower part#68302 valve springs that might work?
They are single /w Dampner springs rated at only 100# closed, but they are fairly stiff. I think the spring rate is close to the valve springs above? I lost my Crower Catalog, and I don't have acrobat reader installed on my computer so I can not get the information from their web page.
I had these springs in my 383 for about 4,000 miles, then I installed the next size up dual springs in the 383.

If you want to try these valve springs let me know. I'll sell them to you for $20 if they work, if not just return them to me.
