Like the big dummy i am,i bought a set of bbm heads and i thought i would use the stock rocker bolts.they were too long and they busted into the runners and made my engine suck oil through these holes and smoke. funny thing is when i tightened the rocker bolts down i did not feel them bust through at the bottom. the resistance of the valve springs,the tension of them tightening down made it hard to tell i busted through.the hole it made was the same diameter as the bolt and when i took it apart i found the little pieces it punched out and they were no thicker than a dime-thin area. that is why i did not know the bolts busted through. i need to take them back off and get them repaired,but for now i used silicone on the bolts to stop the leak. that might be why trick flow heads use thicker rocker pads so this wont happen to dummies like ME.
