Head Stud Kit machine labor

Head Stud Kit machine Labor

Upgrading head studs? Don’t install them by hand. Crooked or misaligned head studs can ruin your engine!

What is this for?

• This is labor only
• For machining 996tt and 997.1TT blocks, liner carriers and heads to accept big head stud kits
• 7/16″, 12mm and 1/2″
• 10mm kits do not require machine work.

What is the process?

• The blocks are cleaned and fixtured to precisely locate and align the oem bores and stud holes
• We find the used blocks to be slightly shrunk after use and not aligning to a standard 118mm stud pattern
• This is repaired when updating to the larger stud kits
• The liner carriers are carefully milled using piloted counterbores
• The tooling can follow the original hole without breaking through the thin walls near the lower o-ring grooves
• Cylinder heads are the final machine process, requiring the holes to be oversized for the big head studs.

Where can I see the process?

• On our YouTube Channel!
• The video below is both for Boring and Head stud machining.  Showing the case only.
