Not sure I'd use SS in aluminum heads. There's this galvanic corrosion that occurs that make them less than wonderful to deal with long term....

After some learning experiences, I now use the Stage 8 Locking Fasteners. They're a bit of a pain to install the first time, but have cured the leaking header backfire blues once and for all.

Whatever you do, don't even think about using the split-lock bolts (the ones with the tiny allen screw in the center to lock them); they ate the threads in my aluminum heads! I did notice they looked like taps anyway... Then to add insult, one of the little allen screws fell out after about a month! 'nuf said.

Try the Stage 8s, you may like them.
