was just driving along friday the 13th when all this cr*p happened. put new coil and condensor and set timing and synchronized k-fish, etc.....but pulling 2 and 3 and no difference....and yes, they both have spark.....i'll set valves in the morning but i think i've got a blown H.G.......no smoke or anything but what else could it be? stuck valve in 2 cylinders at the same time? doubtful. will try comp. test later tomorrow.

You say you pulled the wires and no difference. Dumb question, but did you cross the wires and reconnect them to see if maybe you just crossed the wires when put back together(ask me why I thought of this)
