Thinken a head.Head gaskets.

Looking for your thoughts on Head gaskets.I have all ways used the Fel-pro blue,never payed attrition to thickness,its a stock bore 360,is there a thickness that would give me a better compression with out any lineament problems.Intake,heads have never been milled.Also don't want to play with push rod length keeping things simple and stock.Thankssssssss.
