Quick valve lash questions...

K.. so i tend to overthink and make myself nuts.. my 318 has a roller cam with oem lifters, trick flows and mancini 1.5 aluminum rockers. I have had valve noise that i have been chasing i have lashed the valves 3-4 times now 1/2 turn 1 and now 1 1/2 turn a full turn should be .040 so right now i should be at .060 preload.. doing searches i see guys saying .020 is plenty, mine at .020 sounds like a slant 6 that was never taken care of.. And i see posts saying .080-.090.. i don't want to go that tight really..

So at .060 the noise is there but it's pretty quiet, the sound is uniform and not like 1-2 lifters clattering so it's probably fine. One thing annoying me though was when lashing some of the lifters don't seem to bleed down, like 1/2 turn and i hit resistance and had to put some decent pressure to get the 1.5 turn in.. My main question is will they basically self adjust the oil in the lifter on startup even if they sat for 2 months and some didn't bleed down? I have no popping in the exhaust or intake so no valves being held open at all. I just want to verify.. and next time i am 100% going solid, no guessing and preload **** :)

Only other issue now is my carb is still crazy rich at idle, like melt my eyes out rich. Gonna take it apart to check float levels at a later date, and get a pressure gauge to check pressure, have read that the street demon doesn't like a lot of pressure.
Burning your eyes? What's your fuel pressure? and what kind of a carb? Also, what brand and heat range of plugs.
