Another Stuck Head

[Fillinjc]

Hi,

I know there are threads posted on this topic on this forum and others. Only out of frustration will I start another. Been working on removing my head off and on for several days now. Continuously spraying the studs with penetrating oil. My latest attempt has been with a jury rigged puller using some scrap channel (pic attached). I can see light under 7/8's of the head. But the stud on the front corner by the water pump isn't budging. I have rapped down on it with a brass hammer. I have tapped around the diameter with a punch. Would a puller from the Model A suppliers do more than my makeshift one? Any other suggestions? I can't see the rope in the cylinder trick applying more pressure than I already am.

Thanks,
Jerry
