Default Re: Head Studs or bolts, which is better ?

Studs are way better, more trouble but way better. Anybody that stears you toward bolts is lazy thats the only good explanation. On my aluminum heads (Sharp) I open the bolt holes up .015 with a step drill. I raced blown hemi's and chebby's for 30 years and a nitro hemi for 6 years and never had a head gasket problem...never! All with studs. My flatties are leak tight. I use aviation Permetex on the coarse end of the stud and screw them in by hand, double nut and lightly torque with a hand wrench, I use a little white lube on the fine end and high quality nuts and washers, Torque to 55 to 60 pounds is steps. Re-torque as often as they move.
