So now that we've just made a hole in the head,
obviously we've got to fill it up
Including the shaft bushes, the bore diameter is just over 8mm
The depth is <38mm to the inlet port
So I chose a 10mm by 35mm bolt to fill the empty bore
The masking tape is set at 35mm
Drill down 35mm with an 8mm bit
Luckily the alloy is quite soft
Only had to use two taps, starter and plug
Tap the thread
Wind the tap in until the tape touches the manifold
Apply
Stud Locker to the bolts
And there we have it
