Whats the stock deck height on a 5.3 trying to figure compression, .05 milled seems to be enough to get around 10.5:1 is this right?

Whats the largest size valve that can go without replacing seats and being shrouded?

thickness of stock gm gasket?

Which cam would you pick for an na 5.3 10.5-10.8 to 1 compression, larger valves, slight polish, springs good to .6
truck has 3k stall and 3.73 gears, ext cab z71 weight around 5300 lbs.

Been looking around 218 to 224 duration 112 lsa; thinking .53X to .57X should be good on lift

this is an everyday driver want to keep power between 2k and 6.3k
