Their FE kits are designed for iron block/heads and don't "fit" aluminum motors.
Aluminum heads/block motors are a different animal, especially with the intake bolts. The "crate bolt" ARPs just don't grab enough aluminum threads before they pull those few threads out. That's why I
NEVER use bolts for my FE intakes. I custom make my own stainless studs. Since doing so I've never stripped an intake thread and it gives me attachment points for throttle linkages, halon systems and the like. They also stay torqued down better, requiring less after-the-job wrenching too. Leaking FE intake gaskets are now a thing of the past
