While still planning the configuration of the engine rebuild I have just started, I am concerned about the extent of port work needed.
Having noted stories about the amount of time and/or $$$ the port work on a Weber Head can be, I am curious if anyone has used ExtrudeHone for this? [It is now called “Kennametal / Extrude Hone” since being purchased a few years back.] I have found no threads mentioning this at all. They do list facilities in England, Ireland, Germany & France, as well as the one nearby in Huntington Beach, Cal.
Has anyone heard that the high pressure applied in the ExtrudeHone process can [or has?] broken the relatively long & unsupported Intake runner casting in the Weber Head?
