damn holyman, that piston looks like hell, go with the weisco kit for like 180 with everything u need, boring should be 40 a jug, new head off ebay if u messed up ur old one 20, bout 5 hours of time to do something like this, if u work on engines like that, u got the manual so its easy, but def check those pistons, and flush out the bottom end with gas, so u know nothings down there, so ur lookin at 300 tops for the full top end rebuild, unless ur cranks gone
