I have used a comp cams xe250h, x4250h, and xe262h. I have also installed two xe250h for friends. They all ran great. I never noticed the "noise" in the xe262h but in all the others I could here the comp cams xe sitting the valves down hard on the seats. Switched to Lunati 60103 in the 69 and I have been very satisfied with it. I agree with Lunati being a more modern grind and the close the valves a lot softer than the comp xe series. Based on the stock nature of your motor and the rpm range I would recommend the Lunati 60100. Definitely replace the springs!
