FWIW different brands of rocker arms will often have different patterns across the valve tip even w/the same length p-rod. For "Smokey" fans, he talks about this in his Power Secrets book. Said basically if you didn't see what you wanted after adjusting the p-rod length on one type rocker, change the brand and see what the results w/them were.

Now that's not going to be an option for most guys, but it does show that there can be a difference in designs between the various makes.
