Helpful Notes
- Machine work required: Fire-ring builds need precise receiver-grooves cut in the head and/or block to the correct depth/width. Use a reputable diesel machine shop.
- Always verify ring protrusion, surface finish (RA), and torque procedure with your stud manufacturer's spec.
- Intended for high-cylinder-pressure applications; for mild builds consider a standard MLS head gasket with studs.
FAQ

What hardware should I use?We strongly recommend ARP 625+ or ARP 2000 head studs for best clamping under boost.
