well guys, i just recently tore apart my engine becuase of a head gasket leak, first picture is of my engine, i completely cleaned everything except for the pistons that were farther down in the block in fear of scaring the the walls. Everything is clean, no sludge no nothing, block where heads bolt on is as smooth as a babys butt. Second picture is my little porting job i did on my shortys. I opened them up significantly and took the ridges out of them... sorry for the quality of the pictures, only thing i have working right now is my credit card digi camera =\
