Plans are to bodge a 1275 head on tomorrow to get it running. Probably wont mean coming off the road, but if i can get it going for free then thats not a bad thing!!
Also was cheered up a bit today. Looked at the XE pistons today in a bit more detail, and they turned out to be the superior forged items!

Means I've pretty much got a decent base engine to tune now, with early light crank, light flywheel, forged pistons and later tensioning system. Need to ring SBD up sometime soon and see about some metal idler pulleys. The standard items are cheap plastic crap that tend to explode when you least need it. Result = lots of bent valves and chunks out of pistons.
