ls7 lifter preload on Iron block

Hey guy's, been searching around and read a few threads of people running less preload on iron blocks vs aluminum blocks due to expansion..

So any iron block people hear want to chime in on using ls7 lifters on their iron build?

thanks

I'm running .060-.080". It's a valid theory on solid roller setups, we run less lash on iron blocks with and tighter with aluminum blocks, but for a hydraulic roller with LS7 lifters, it may not be too big of a deal.
