Used small pry bar to gently remove scavenge pump. Area is very tight and required lots of finger control. Cleaned and inspected assembly while it was out. Reinstalling was slightly difficult due to alignment with cam sprocket. I did not use cam/crank locking tool; I don’t see why this would be required for this task with this engine design. Anyone with large hands will struggle with this project since space is so tight.
With regards to header gasket replacement, I sprayed wd40 one day, CRC freeze off another day (that stuff stinks), tried removing bolts but they were tight and I was afraid of stripping/shearing, so another day started car and brought to operating temp then attempted to remove but they were still very tight. Given that engine was hot I gave the bolts a little more muscle (about 40lbs) and they all came out without damage. Replaced gasket and reused bolts coated in thin film of anti seize.

Did your scavenge pump stop leaking? I'm having similar leak and read elsewhere the bolts can leak, but rarely the gasket itself.
Did the exhaust gasket stop that leak as well?
