Head tubing report. 80 grit flex hone report
This is an industrial Ford 5/8"-7/16" iron guide in the mule Olds head, offset from the OE....which of course varies from port to port...so the potential depends on what the worst of them is. But it allowed this;
Left mirror port I hit the roof for some "grind & find"..red streamer water, green leaf rocker screw, purple Doomsday Cult shroud lots of meat. The one on the right is sleeved with the guide till I just popped thru', combined with the other stupid stuff I'm doing to it, ..We'll see..
