Stripping down an old cylinder head, both exhaust valves are tight as assholes, siezed basically. Any advice, have had penetrating oil on for about 24 hours now, not tried a blowtorch as don't wanna risk cracking the head unless last resort!
Is this one for a machine shop?

better than a blow torch which is concentrated heat why not try popping them in the oven for a bit to get an even warm up.
an VW/engineering firm could probably get the valve guides and valves out complete and then have new guides fitted.
