I took the cylinder heads in to get looked at.  Carquest on Oxnard St in Van Nuys back on 7/23/2010.  They lost my paperwork.  I didnt realize it was so easy to misplace a couple of 25 pound pieces of cast iron that are painted bright orange.  They finally found them.  Anyway, valve stems and guides are shot, $300 to get them rebuilt or use them in exchange for new ones.  My dad, my brother Marc, and I are trying to decide a course of action.  Dont hold your breath.  Caution dictates that you measure twice, cut once.  Walters Family saying "measure twice, step back, measure once more, call your buddy to come over and double check your work, measure one last time, then think about whether you ever even wanted to cut in the first place."
