@65redspit -Yes i plan on re-torquing it , I'm a little nervous about the rebuild !
I've only just bought the car and don't know everything about it , but every time i check something , its different or modified. The block is the short crank GE from a herald, and the head is the big valve. On my first outing 2 miles down the road it was steaming and overheating , under the bonnet i could see the head gasket bubbling away at the back end and some coolant leaking from a block core plug !!!! when i removed the head and was cleaning it up , found a small crack between 3 & 4 chambers GRRRRRRRR so i have bought a second hand head same numbers big valve , but this engine i have has been honed on the cylinders and as it had shims under the rocker , i'm guessing its got a high lift cam or has been skimmed before , so mmm little unsure how it will play out.
