Do you know what those numbers mean? Most likely it's just the thread pitch, shaft length, and the shaft diameter. How do you know the strength and temperature tolerances are the same? I would hope you at least used Grade 8 bolts.
I don't even see the point. The Comp Cams bolts are only $20. Why not get something you know is intended for that setup? The reason they're more expensive is because of the hardening processes used since they're in a high load and high temp application.
