Long over due update....
Thanks for the recommendation Winston.
Ive got my heads and rotating parts back from Fiennes Performance.
After talking to Angus and hearing that Gary had used them, I went to these guys who were a delight.
Of course it wasn't all plain sailing, my new valve guides needed to be a larger oversize so they needed to be
returned to John Willhoit in the States who was also very good to deal with and he sent some larger sized guides before he received the returned ones.
So now the heads have new valve guides and new cut valve seats

Ive put the new cam on the old cam gear

I measured the compression of the springs, I think in newtons but not sure. Either way I found the weakest to the strongest large springs and the same for the small springs.
I should mention they are dual springs to make things clear. I put the strongest large spring with the weakest small spring and matched the rest accordingly as I couldn't afford
to buy more to get a perfect match.

Managed to find a couple of weak non car springs to be able to measure the spring heights and work out the shims needed

Once I had every thing measured and sorted and then set to installing the new valve springs........but
the valve spring compressor I had purched and used to remove the old springs was proving useless. Once compressed it
would not hold a straight line along the axis of the valve stem, or in other words the spring went on the wonk. So I
was watching the little timelapse PRS video of their engine build and spotted their builders compression tool, and bought one of those made by Facom......
What a difference.....

I was able to fit the valve collets without F-ing and Blinding

So the next job is to measure the combustion chambers and see if they need equalling

and here's a shot of the the balanced rotating masses
