wnt to the best machine shop (here) and they said that they couldnt to it bcause it went from the cmbstion chmbr to under the exhst vlve seat. the guy said he actually had an extra one for $350 that had been rsurfaced and valveseats grinded(no valves) customer didnt pick it up after a year. they resurfcd it again for me and I only found one crack, it was bout qtr inch long and on the big waterjkt hole in the mid of the head. did not reach the combstion chmbr. the guy is honest and says that is shouldnt be a prob and says to thinnk it over and bring a mechanic to look at it with me. just wonderin what you guys think. thanks for your qck reply.
