Re: 1380 build

With a 1380, there is not much material left between the bores for the head gasket to bed on, so both block and head faces must be perfectly clean and free from even minute blemishes. Thanks for the tip, its going to be skimmed until it's right. I dont have vizards book and so many conflicting repo...

Re: 1380 build

We have a 1380 in our Minor, and it has Omega 11cc dish pistons in. With a cylinder head volume of 21.5cc, this gives a CR of around 10.3:1. The head is a 12G940, converted to 11-stud and worked on by Peter Burgess with Cooper 'S' MkIII size valves (1.4" inlet and 1 5/32" exhaust). The bl...
