Well I took the head to the engine reconditioners in Cairns the other day and left it with them. I went down today to check on how it is going and was told that there was a crack in the head. They have rung all their suppliers and contacts about obtaining another head however were just laughed at when they told them it was for an F motor. So I rang a mate in Ipswich who owns his own 4wd diesel business and he made a call to a mate of his who runs his own engine reconditioning business. Well supriseeeeee he has a fully rebuilt F motor which he rebuilt for a customer about 3 years ago who never returned to pick it up. It has been rebored, new pistons, rings, bearings, welsh plugs and the head has been also rebuilt. Managed to score it for $1500.00. Just got to get it from Ipswich to Cooktown now. Also picked up a new radiator, brake master cylinder, clutch master cylinder, clutch slave cylinder and have all the brake wheel cylinders fully reconditioned. Will post pics when I get back home to Cooktown.
