There's a set of Kent Cams solid lifters on their way to me now - thanks to Gary C for those.
I'm praying that solid lifters will solve my problems, certainly after discussing it with a lot of people, most reckon that stock hydraulic lifters are beyond their limits at 7,500rpm+.
A couple of photos of how the front end looks now with the carbon bonnet, I'm really pleased with how tough it looks;

And another small contribution to the weight reduction.....I've re-made the Gurney flap on the tailgate in carbon fibre instead of the previous aluminium angle;
