You clearly have a faulty argument and are now realizing that. Would only make sense you retire. Im surprised you didn't earlier. As I already got on Nick for is the fact that spinning higher will result in a new SB to be able to be afraid of the expansion of the rods to cause any damage. According to nick a steel rod stretches .025" at 7,000 rpms. That still leaves you with .025" of clearance IF YOU can spin it that high with steel rods. Understand? Also if installed correctly and turned the engine over by hand you can tell if there will be PTV contact. If there is then you degreed them wrong. If there aren't any then your good to go.

I have already answered that question earlier in this thread.
You realize .005" is basically the thickness of a human hair? As you start spinning higher rpms that clearance only decreases. I have personally talked to a buddy of mine that has seen what the CMS Stage 2 did to a motor. The thing Nick has said before is that the pistons and valves are so hard that you could have PTVC and not know it.
This argument/debate is really pointless. You aren't going to change your mind and you aren't trying to see from the point of the people who don't want to run cams that have that little of clearance.
I'm putting in my notice that I am officially retiring from this thread.

This thread really got out of control and I am stepping out of the bitchfest myself but I do have to respond to the above. This is the wrong way to test for PTV as you can depress the lash adjuster 0.080" turning the motor over by hand as there is no oil pressure to keep it pumped up. You will never know you had PTV doing it this way. Only way to test for PTV is with a solid lash adjuster and either a dial indicator or Silly Putty between the valve and piston.
