Hi everyone.
My mate Neil asked us to repair his warrior head because the head gasket had blown whilst he was racing at Lydden Hill Circuit.
He noticed that the head finish was in a bad way from previous machining. We vac tested the valve seats and discovered that they wasn’t holding vacuum.
The valve clearances were all over the place too. We repaired the head, recut the very bad valve seats and reset the valve clearances.
Neil brought the car down to us to do the cam timing, he took it to the rolling road and it made 295bhp a 25bhp from the month before.
Thanks for watching.
James
