Wrap some 120 sandpaper around the dowel before you grab on with the visegrips. It will help it grip.

Goodson tools has a collet style dowel pin puller that works great. On the really stuck ones coat the dowl with a little lapping compound for better traction

Got the stubborn little bastards. Patience was an understatement and certainly not my strong suit. Appreciate all the suggestions.

Map gas torch is what I used. One came out easy but the other three were hand to hand combat. Thanks again.

My son bought a big block of bee's wax for like $6 at the swap meet . he cut it into strips and put them by the saws and vise .
I think the problem is that it's easy to get the dowel pin too hot . I use the wax to cool it down and it also wick's itself in the hole providing lubrication for the pin . If it still wont go , I get it all really hot and put the hose from a nitrous tank aiming at the pin , shrinks and will just about fall out by itself ...

Ive always had success using a Brass rod and tap it in 4 positions and they have always come right out.

I like the idea of nitrous. I was thinking about maybe a piece of ice but figured it would melt so fast it would be a waste of time. I used almost all of above ideas except collets. They are like sleeves. Some release easily and some don't. This particular block had blown a head gasket and ran for a while so crank, rods, and sleeve were ruined. Got the sleeve in and was ready to bore when I noticed that during sleeving process another sleeve had turned. Finally got sleeves in proper locations and last night I got it decked. I about took a whippin on this one but looks like it's finally going to work. Thanks again for all the suggestions.

Vise grips / slide hammer. Either weld a coupling nut to the side of pair of vise grips and thread your slide hammer into it or take the adjusting screw out and use a long threaded rod as the bar for the slide hammer.
