Spent Saturday removing the head, quite a challenge !
anyway, though I'm very pleased with the general condition, there are a couple of odd questions....................
it appears to have had a re bore ? see the stampings, but is it unusual that the two center cylinders are larger ? what difference would this make, and is it a problem ?
also note that all the valves are marked, I thought only exhaust valves were marked ?
all opinions / advice welcome
