Header Bolts to use

[J. Caraco]

Anybody use or can comment on Bo's header bolts? Having engine rebuilt and the old Rod's header bolts not so good anymore. I do see an old thread where someone used the socket head ones and safety wired them. Mine constantly back out. If not Bo's any recommendations?

I actually wanted to try the stage 8 fasteners on the rods header but.... don't fit. I had to get another set of allen bolts machined. That is the only thing I can say bad about rods product.

Bo's bolts don't work with my Rods header. Then I went to the hardware store and got stainless bolts and turned them. Then drilled and safety wired them as mine fell out too. If you go this route drill for safety wire before turning the tapers also Cobalt or better drills are recommended.
