If you do the Stealths, please please please replace the springs/locks/retainers before running them. I did the locks/retainers before install and then broke a spring less than 2,000 miles later.

I have 10° comp cams retainers and locks, didn't know the springs should be replaced too  :o I bought a set of comp cams 911 springs that I was going to use on the 906 heads... assuming these springs will also be a good choice with the stealth heads  :shruggy: https://www.summitracing.com/int/parts/cca-911-16
Thanks 68coronetRT


Sure, the Comp 911's will work fine on the Stealth heads with the 10* retainers/locks. The Comp springs are superior to the stock "Stealth" valvesprings so if you have them you might as well install them  ;)

Those 911's are fine with the Crower 271 cam....no worries there  :2thumbs:
