Removing Head Bolt

Seems like I have ran into this before on a 340 head back in the day.
Unload the rocker shaft and see if you can peck the springs out of your way dustermaniac, and if that don't do it!! pick out a socket of your choice and walk over to your bench grinder and take the first 1/4 inch of the socket down Very little :toothy9: and remove that puppy :glasses8:
Wear your safety glasses, or put it in a vice and use a hand grinder.
