Tony - a standard T/A replica hood was tall enough to let me run Stage VI heads (raised ports), a Victor intake (comparable height to TF) and a 3" drop-base air cleaner. Probably another 1/2" clearance w/ standard-location intake ports; no room for spacers or taller air cleaner w/ the Stage VIs (very tight fit).
