If you are using true ls6 heads with the light weight valves that pr is WAY too long. Their valves are .100 longer. Otherwise the difference in the ls7 lifter vs the ls1 isnt that much to necessitate a longer pushrod than 7.400.
Normally a 7.400 pushrod will get you in the window of preload for nearly any cam unless they are the stock ls6 cam or a regrind with untouched heads. If they are milled or you are using a thinner gasket then youll want to measure.
