Re: Stuck valve?
If the guide is moving with the valve it is shot already.
knock the retainer and spring off and push it out with the valve.
After separating the guide from the valve you can assess the situation.
It is not uncommon for some of the guide holes in the block to be loose/oversize.
If the guide is still good ID, you can knurl the OD slightly and loctite it into the block.
I have never had a block with consistent guide holes, always 1 or 2 too tight and 1 or 2 loose requiring the knurling tool.
I am actually impressed for the age how close they are.
