No-Lead Conversion Posted by Freight on November 08, 1998 at 19:03:46: Anybody have any probs. with cutting the holes for the seats. IE. run into a water passage or imperfection in head from casting or cutting wall thickness between water passage and seat too thin?? My machine shop here in the IIIW is concerned. I cannot imagine probles would not have been posted on the board or others before if this was common. In any event I have told them to heat the head and freeze the seat before pressing in to preclude alot of psi. stress. Any thought? Advise? Ideas? Etc would be appreciated ASAP as the cutting will begin soon! Freight
