Re: Replace head studs with bolts?

Forget about changing from studs to bolts, not a good idea!!

Purchase any required new studs from Kanter Auto or Max. I've used Helicoil to repair bad threads in the block, there are other types as well and I suspect most any of them would work. Install the studs with thread sealant, I prefer old-fashioned gasket shellac (Indian Head or equivalent). You can get thicker washers, even aircraft quality ones if you wish with both sides ground flat and parallel to very tight specifications, from places like MSC Industrial Supply, and probably McMaster. For proper clamping force you'll want nuts that are 3/4" across flats and suitable for 65 lb-ft of torque. After installation, retorque after 15-30 minutes of running, again after a few hours, and again annually until no further tightening is needed.
