yes, if this basically hapened when you adjusted the valves, its possible to over tightened the valve lash , so that when the engine is running the oil in the hydraulic lifter (esspecially with lots of oil pressure) wont bleed out enough , and the valve doesnt close alll the way, causing the flame front from ignition to escape past the exh valve down the header. This also means that you have basically experienced zero lash, which could cause bent pushrods, broken roller lifters, etc...ussually the pushrod gives first. If this is the case, it sounds like it would just barely be on the edge so I say hopefully that everything is still ok. Ofcourse I could be entirely wrong.
