Yup, thats my post on those forums.
Yup, over-rev'd and damaged what was thought to be 2 valves but I now know it was 3 valves (2 inlet and 1 exhaust). I'm having the heads sorted via CHI and are also doing some while we are there kind of things. No sense not fiddling a little. Engines not harmed but heads needed a very very very slight tidy, 3 valves, 3 guides and 2 seats.
This is where I am at with the XB (my toy). I'm upgrading the valvetrain for silly rpm (I mean silly rpm). So totally new valvetrain less valves. Also reducing the combustion chamber for higher compression. Yes, 11.2:1 works but I want to push limits a tad more. Fitting a rpm limiter/ignition amplifier. Fitting caltracs. Removing lowering blocks and fitting superlow leafsprings. Debating whether to do the tailshaft at the same time. Then throw it back on the dyno to hopefully get the 300rwkw I am after. Then drop the pipes and see what happens. Then off to the track to blow my current pb 1/4 time out of the water again.
