799 Head Question

Does anyone know the maximum lift on the stock 799 valve springs? I bought some 799 heads, and also got a cam package from texas speed with the ls6 springs. I am just wondering if the stock springs on the 799 are the ls6 springs. Just wondering if I should put the new ones in or if the ones already on there will work fine. the cam lift is .550

The 799 heads on a Trailblazer SS had LS6 (yellow) springs, not sure about any others

They are different springs if they are truck 799 heads. I put the blue ls6 springs in my 799s for my hotcam.

I guess I will just go ahead and change them just to be safe. I am not sure what the heads were on before. I got them off ebay.
