Just wondering who has done this and with what success and what needs to be done. I found out my head is cracked (big surprise) from my 87 tc. My bottom end is ready and my machine man found a crack in the head when he magna-fluxed it. Apparently that head no longer exists around here so I'm guessing i gotta find another route. I seen that it was possible to use a N/a head with some machine work. Just wondering who has done this and how. Thanks
