just for your info this cylinder had been replated ...not by max power though...it has the usaul intake casting bridge flaws ,, and the breaks in the exh boster ports are the worst i had seen ,, some one sold me this on fleebay...o well ifigure they will have the mojo on them ,,not me i cut it up so no one else would have problems and to learn from it ..making the best out of somthing bad
