Rob....sounds like those cam specs will work well for you.. Now, I'll admit Im not a comp cams fan at all.. It's mostly customer service, and tech advice like you described above. Before you order anything, at least make a call to Lunati Cams and speak with Steve... Check on the Lunati/Ultradyne cams, and especially the newer Vodoo series. They will make more power than the Comp lines, and will be easier on the valves also. Try it, I think you'll be happy. And removing the inner spring (if you have one!!) depends on the cam specs. Check with the cam tech on that. Follow their advice on springs and break-in, at least that way, if you should trash the cam, you can say you did everything you were supposed to. John
