Head gasket time

[Agemax]

H I live in Coventry and had a bbb of a job separating the head and barrel I used a splitter tool from side to side it has two blades that expand as the screw is turned. I had wellseal on the barrel to crankcase joint it took hours to clean off.
I am skimming the head to get a clean fix, do you know how much I can take off? it looks somewhere near so should be a light job.
Good luck Noel

after you have thoroughly cleaned the mating surface measure the head mating surface. this will tell you how much you need to remove as a minimum, if any...........
