Here is my question , will ls3 heads live with 18psi with out pushing water ? Or am I better off just dining LSA ? And who here run the bad *** valves in there heads and who run stock valves . Just trying to determine what to use for 408 with Novi 2200 supercharger

Go with LSAs with stock LS3 valves. LSA heads are better than LS3s on boost.
