Head studs
I'm installing a Brumfield High-Compression head (not sure if it is 5.5 or 6.1).
Should I replace the original head studs with Chrome-Moly or Grade 8 bolts? Or re-use the original stus?
Bratton's has Grade 8 with rolled threads, guaranteed not to stretch and Snyder's and Bert's have Chrome-Moly, guaranteed not to stretch.
I read here that you want a little stretch. What is recommended?
Also, with the stronger head studs, they recommend 65 ft lbs of torque.
I broke the ear off my early 1930 style water neck at 55 lbs.
Thanks.
