So you see how I did this from this thread

valve guide extraction

I tightened the nut at the top and it pulled the valve guide up and out. The spacer at the top was large enough for the valve guide to pull through. Large washers stacked at the top and where the spacer then rested on the block.

I used standard grade 2 threaded rod. You can get hardened threaded rod from McMaster-Carr. The Grade 2 was just on the edge so you probably need stronger.

Here's that link.
