Can I reuse the old head bolts in my Ford 6 cyl turbo when the head is being refitted?
No you boxhead, you cannot – the OE bolts are TTY (Torque to yield bolts) and once they have been torqued in place they have yielded which means they have exceeded the plastic deformation state – in other words they are stretched. We suggest you fit a set of Atomic head studs. They can be reused many times and apply approximately 30% more clamping force (at the same torque) than a bolt. If you are really going to crank things up we suggest you upgrade to a set of our 14.3mm head studs. They require drilling and tapping of the block to fit, plus enlarging of the clearance holes in the head, gasket plus a set of our oversize head to block dowels.
