So my 95 lt1 only has 60k on the engine and at around 3k it pulls 10* till about 4k then from 4k to 5800 it pulls 5* to 6* of timing I do have headers but just I cannot hear them hitting anything I have changed both header gaskets and I run 93 and it tuned for 93 the engine does make a fluttering/ticking sound when it gets up in the rpms but does not sound like knock. Any suggestions rockers lifters is it detonating? I can post a video of the sound at a later time and I'm using data master for my programming if that matters
