EDIT: Head is toast. Looking to source replacement ones. So I'm tearing into the FAT perfomance 2.6 engine. I was going to try to run it, but before that went to perform a leak down and saw a gaping hole in #4 next to the plug. I just removed the head and it looks good other than previous welding I assume FAT did when the built the heads. There is little material amount between the camber and the edge of the head due to the cut of 103 P&C. Is this just the evil of hipo engines or are better options out there? Should I have these rewelded OR buy new 103 cut heads? Who out there is running big power? Also I know Raby spoke highly about FAT engines, but damn did they love RTV.    |

Does this mean the case was opened up for the 103 clys?
