I am pleased to report that we have now wrapped up this Stage One rebuild and we will be installing the engine back in your Mk II shortly.

We have now completed the machine work on your short block and have the repairs to your cylinder head well underway. The cylinder head was warped and had significant corrosion damage. It also had some inappropriately sized valve seats which meant that the seat pockets had to be welded up and re-sized. Number six chamber also needed extensive welding in the hemispherical dome to cure some deep corrosion pitting and literally every water jacket had to be welded up and re-shaped on the mill.
