Well I just came in from offshore today after my 14 days working, I now have my 14 days of daqys off starting today. Well anyway I went and checked my numbers on those old "307" heads I had wrote off as non matching numbers. The origanal book I was using said "307" but Mortec says they are 307 and 327 heads. 3917293 on both heads, L47 on one and L67 on the other, so I guess I do have all the original parts for the car. well it will not get built by me, maybe my son will one day, he is 4 years old and already trying to talk me out of the car.
