I like the 20-50 Valvoline for an unknown engine history. I suggest driving at WOT (wide open throttle) as often as possible for the next several miles. If in town do low and second gears at WOT. Go to WOT up to about 3000 RPM and coast down to slow then repeat, repeat, repeat. The theory is to load the rings as much as possible with combustion pressure and hope they will "seat" to the walls. DO NOT allow the engine to overheat.

Is the tailpipe showing oil drips and build up? Does the breather indicate heavy blow by? Is the proper crankcase breather system in place? Is the stock fuel pump in use? Does the oil accumulate gasoline or smell like gas? When the heads were off could you see wet, oily, chambers?

As a previous post indicates, it is important to have clean, flat surfaces for the head gaskets and to RE-TORQUE the fasteners multiple times after heating and cooling cycles.
