Ok guys got some awnsers now.... in short the headgasket did not fail @ all so i thuoght WTF!?! is gone on here???? well i figured it out bleave it or not one of the exhaust crossover block off plates i had made to block the cross over completely is my offender! after finding it missing from where i let it i grabbed my plyers & started folding out the bits of steel out flat & suer enoph thats my culprit!!!!!:cussing: I have not a clue how in the world it managed to go past the exhaust valve scott free not so much as even tutching the valve or seat in any way then go for a ride until i removed it from the cyl. & bleave it or not cly looks great chamber looks great the olny thing that took any kinda damage was top of the piston a little. So now im looken for so intake gaskets that already have block off built in. heres a pic of block of plate.
