Help me identify Crane Cams LS1 dual valve spring I bought a used set, of assembled LS6 heads with these valve springs. According to the seller, they are Crane Cams dual valve that are rate @ 0.650in of lift. Only problem is, I don't know anything else about them. I narrowed it down to two possible choices of what they are. Either part # 144833-16 or 144832-16. The only clue is that on one side of the valve spring is a yellow stripe and on the other is a blue stripe. Any ideas?

Check the seat pressure if you can. I have the 832's and they are only 110 at 1.800" installed height. I ended up shimming mine .060" to get around 130 on the seat. I think my springs had some blue and yellow markings on them, but don't quote me on that as I haven't messed with them for a few years.

I want to know if I have either part # 144833-16 or 144832-16. Looking at these valve springs there is a yellow stripe on one side and a blue stripe on the other. Also I want to know if they would be fine running the Thunder Racing LS2 cheatr cam?
