Custom headers and cam timing are next, if that doesn’t break the 6K barrier then intake revisions (plenum and throttle bodies) are probably next. For now I’m just going to drive it and enjoy the ride. Just had a great time at Japfest Goodwood followed by a track day there yesterday. Black Sunshine got a lot of attention and held its own on the track, what a great car to drive!

did a compression test today.
i think all is well
all drivers side was 12bar- 176psi
all passanger side was 11bar-160psi
i think my timing belt is out as the cas is adjusted to nearly the end of its travel.
i would hope that after changing the belt they might level out? as one bank would be running more overlap hence a lower compression. make sense?
if the head gasket had failed i would expect either one or two cylinders to drop
