I got my block back from Serdi who sleeved the damaged number 2 bore. They also honed all four bores, so the block is looking lovely again. I left the protective coating on for the photos, hence the yellowish colour. I've also got round to ordering replacement rings, so things should start moving again. I still need to source some dowels to locate the head as Burtons are out of them. It seems Ford never fitted them as standard, which explains why the gaskets never have clearance for them. It seems really penny pinching, and I'm not happy to leave them out.
