Default LT5 Valves

Do LT5ís ever require any valve adjustments? If so, How is it done?

The LT5 has hydraulic lifters, no valve adjustment required.

I think a few of the race engines and for sure FastLane "the hard way" used solid lifters

stockers do fine up way past redline. I've kissed 8k a couple of times and can see where the valves started to get away and kissed pistons

fastlane revved to 9k plus with custom build chains that he changed often as a valve adjustment is manually shimming the lifter *engine pull*
