Helicoil5546-8 M8 x 1.25 Metric Coarse Thread Repair Kit

Q: Are the inserts stainless steel?

Yes! If they are some other metal it will say on the package.

Q: Will these hold well in an aluminum cylinder head to fix 2 stripped rocker holes, and be long enough?Spring psi. is ~450lbs. open.

I don’t know the specs for my psi but I used this set to fix 2 rockers on a 3.1 Chevy engine, worked perfectly.

Q: I need a heli-coil for an 8 x 32mm motorcycle exhaust header stud of unknown thread pitch, will this product work?

I used one for an exhaust manifold bolt on an Ecotec 2.2L engine (2006 Saturn Vue). It was easily installed. The hole had gotten out of round and to large for the heli-coil itself, so I drilled the head for a 13mm hole and used a piece of13mm Aluminum bar, a little over 30mm and drilled that out and inserted that heli-coil. Everything went together without a problem, but it was just recently done, so time will tell if it lasts forever but I don't invision a problem.
