For Sale : Set of Heffner Twin Turbo Stage X Race Ported Gen 3 heads
Heffner did all the work on these heads. These are the heads that come in his Stage 3/X builds.
Race ported including intake and exhaust runners and combustion chambers, with bigger intake valves (2.04) and bigger exhaust valves (1.60), bronze valve guides, teflon valve seats, titanium valve retainers, heavy duty valve springs, heavy duty hydraulic roller lifters, Red valve covers and billet valve cover spacers. The heads have 1000 miles in them after being built.
These heads flow just over 380 at intake. The only reason I’m selling these heads is I want to use traction control and drive by wire on dual e-throttles on a Gen 4 intake manifold which is not compatible with Gen 3 heads.
I can also sell the T&D 1.7 Roller Rockers and Chromoly pushrods if you are interested.
Asking for $5,800 OBO for the complete heads minus the roller rockers and pushrods.
I will add pictures soon.
