I got all the stuff done except plugs 1, 3 & 4. Those seem stuck. I tried to take them out but wasn't successful. Turned them a little tighter and then looser but still no joy. I tried spraying PB Blaster on them to see if that would help but so far no joy. Will spray them once more and then leave them soak overnight to see what happens. Anyone with any bright ideas, this is the time. I would like to do it without breaking the GP off in the head.
