    Holley Systemax head question

    I have pedestal mount rockers on my Holley Systemax heads. They are 1.94 - 1.60 stainless valves. Stage 3 ported/polished. My car never smoked until I bolted on these heads and now it smokes almost everytime I start it. I was told tonight that it is common on these heads and I was told that the fix is to remove the rocker bolts and put black RTV on the bolt and then tighten them back down to spec. My question is this : Is it possible for oil to get through this bolt hole and onto the tops of the valves ? Originally I thought it was bad valve guide seals.
