The Ford Barn - View Single Post - Stubborn Tight 2-Piece Valve Guide Won't Come Out

The block i removed the guide from was a USA model "B" block which I knew had a reputation for being a bit fragile in the upper valve seat area. I had given the guide a few fairly hefty bops but caution crept in and I then drilled it out. it was surprising how quick and easy it was .If it had been an English Dagenham block no doubt I could have hit it harder as they are a much heavier casting with a thicker top deck and not prone to cracking

John in same place same weather .
