Did exactly this myself surprised how much valves were letting buy, just required lapping

Yes, progress is being made. I'll follow up with some pictures in the next few minutes.

The problem is that the car is at my parents, and by the time I've gotten there, unpacked the tools etc, I don't have much time before I have to pack up again and drive back to Northampton to collect the missus from the train station.
So weekday progress is slow going, weekends are better, but also taken up by pre-arranged events etc...

Also had about a week's delay in getting the head back from the machinist...

So I decided to go ahead with the full works on the head, this added an extra bit of time to the machining shop’s schedule and left me time for parts to be delivered etc.

I also decided to replace the CPV seal while waiting (and with the exhaust manifolds removed, it was far easier to get access).

I didn’t have a drag-link socket though, and didn’t want to buy a big flathead socket just to butcher it, so found the closest most ghetto fitting tool I could find…






Picked the clean and shiny head up, complete with 3x bent valves (souvenirs?) and set about winding in some new exhaust manifold studs (a few of the crusty old ones came out as I was unscrewing the manifold nuts)…





After that it was time to clean up the block and refit the cylinder head…

Cheers, Dave
