IwantMKIII told me to talk to you about lapping a head as he told me you used to work in a machine shop. My buddy has a machine shop and is testing out prepping a spare head for me, but he has never had to lap a head or block before, so he doesnt know what needs to be done. Could you give me a rough explination I could relay to him so he can get some practice in on this thing. He has always done domestic with very little import work, and nothing with the specs needed for a MHG on the supra. He is basically giving me a freebie head build to practice some import performance work and get his name out there once my car is done. So any information on lapping the head I could relay to him would be greatly appreciated.
