Mullered clutch 2 litre ABF on twin 40s + Campaign Gearbox

Hi there. Does anybody have any advice on what the best clutch / pressure plate combination would be? I'm running a 2 litre 16v ABF on twin 40 Dell'orto DHLA's and a campaign close ratio box in my 83 hardtop. I fitted a standard clutch / pressure plate in the first instance to get the old girl back on the road again after a 7 year build but 3 months later the clutch is destroyed. Slips terribly in 2nd, 3rd, 4th, and 5th.
I have just bought a standard ratio Mk2 8v gearbox (52k) and was wondering if anybody could point me in the right direction with the clutch because i dont fancy pulling the box again in another 3 months time.
I'm running a standard mk1 flywheel which i will skim over before refitting if its not burnt too badly…
It did go rather well!!!

Thanks for looking.

std sachs 210mm one should be fine unless engine heavily modified, could be oil contamination from worn gearbox seals?
