I got a spare 1.6 head 2 years back and I finally have the time to refurbish it.

The camshaft is stuck in the head and my lifters are all froze in it as well..... (previous owner had it out of the car for 20ish years dry)
Does anyone have tricks to getting the lifters out when they're stuck? I hoping the cam will come right out when the lifters pop out but I can't even turn the camshaft.....


Lastly, I was curious if any of you know where this head came from. I don't recall any of my American heads having "Essex" on them and I was told that the American heads all have rocker bolts instead of rocker studs (this one has studs unlike my 1.9 head).
