not much to update at the moment. but after building my spare head it still misfired on 1 and slighty on 2, took head off again and discovered the inlet valves on 1 and one of the inlet valves on 2 werent closing fully i took it all apart again changed the lifters on 1 and 2 but cant get the valves to close fully. i sent it off to a specialist and bought devil developments valve springs, another mls head gasket and bolts(thats 3 now) new lifters and also grabbed a amal valve to aid with boost control. i should hopefully have it back together soon to get it run in then fit my tubular manifold and find a turbo as my t28 wont be man enough for the power im hoping for. then she'll be off to karlos g for mapping
