Need valve spring help??

I have a 04 Tahoe with 799's milled 30 thous running Cometic .036 headgaskets and a Comp XR259HR Cam. specs are dur @ .050 206/212 Lobe sep:112 valve lift .515/.522 I currently have the blue GM springs but need to upgrade them because A buddy is gonna give me a killer deal on a set of 1.8 Accelerated lift rockers. I was looking for a set of springs but am not to sure about what to use. I ran across some Trick Flows that I was thinking would work and wanted to get another opionion on them from someone with alot more experiance with this than me. Trying to find a spring that will work with the stock hardware also.

Why are you worried about 318lbs? You won't be close to that if your setting up at 1.8. Probably closer to 280-275.

PSI 1511 or PAC 1518 would be my choice. Nitrided beehives. Can be used for probably 40-50k miles on that setup.
