I haven't tried the Scorpions yet. No one seems to know where they are made but by the same token, neither the Ford Racing/Motorsport versions either.

Those I am presently running. Ran Harland Sharps too.

The only question in my mind with the bolt downs is the 5/16" mounting bolts. This is even "refered" too in the manufacturers instructions.

They tell you not to excede a certain valve spring value.

I used a set of the Ford bolt-ons on a 302 and had no issues with them. That was an everyday use truck.

Make sure the threads on your heads are in perfect condition, each and everyone of them.
If they aren't then go a different route.
