stop bumping your thread!!! if noise is what you want, put a comp xe282 cam in........but the whole springs good to .575 lift not what you want to go off of...........personally if it were mine, I'd go custom, there are more benifits than drawbacks. but it's YCYMYP.

damn beat me to it!
upgrade the valvesprings too itll add less then $90 to the build and will make sure you dont float a valve (i have no idea what the seat and open pressures are on the heads).
MAKE SURE you measure ptv clearance.

call comp cams and tell them exctly what you have and they will grind you one it would be better than guessing and people telling you what they think. when you build that kind of motor and on that kind of money just call the folks that make the cam and they will know what you need!
