Big Block Cylinder Heads "915 vs 906"

True story...even if you're buying the $1000 Stealth heads, it's been made pretty clear on these forums, bolting on a set of new aluminum heads without cleaning up the bowls and seats, a quick surface cut to ensure straight decks, plus checking installed heights on the springs is borderline negligent. Those processes, where I was at before, would be worth about another $350 for a complete set of V8 heads.

Correct,

One of our customers bought a set of Edelbrock RPM 440 Performer Cylinder Heads for $1400.

He thought he could just bolt them on the 440 Short Block we built for him, 'right-out-of-the-box'.
