Sold some parts recently from spares in my shed, so have acquired the following for the motor:
AU2 multi layer steel genuine ford headgasket - this should stop the motor from being able to do a headgasket. I still need headbolts.
Nason Timing Kit (new chain, chain guides, new tensioner). Normally I'd just leave this be and wing it; but I don't have any sets with unbroken chain guides.
Looks like I can at least begin to put together a motor now.
