My question for those who have gone shimless is how long until you have to tear down the head to replace valves because the lash went out of spec? Do VVL heads have a worse likelihood of spitting shims than a solid lifter DET head? I never once spit a shim in the 13 years I've had my DET head (spun up to 9k with solid lifters, but mostly between 8-8.5k), but I'm in the process of switching over to a P11 head now.
