Trick Flow® Twisted Wedge® street/strip cylinder heads will revolutionize the Mustang scene once more with the debut of our newest high performance heads. The Twisted Wedge® heads feature a combustion chamber design, coupled with an intake valve moved to the opposite side of the camshaft, just like the 3V heads on 2005 and later 4.6L/5.4L engines. The benefit is a dramatic increase in mid-lift airflow, plus increased piston-to-valve and valve-to-bore clearance that allows for the use of higher lift cams and larger diameter valves without having to alter the bore size or fly cutting pistons. The Twisted Wedge® street/strip heads fit all 1996-2004 4.6L/5.4L 2V Romeo and Windsor engines (no modifications of the oil passages in the block are required), and all OE-type 2V camshafts, followers, lash adjusters, and valve covers bolt right on. The Twisted Wedge® street/strip heads for 1999-2004 PI engines have 38cc combustion chambers and deliver approximately 10:1 compression on a stock short block. Heads for 1996-98 non-PI short blocks have 44cc combustion chambers and also deliver about 10:1 compression.

Other important features include:

* OE PI (Performance Improved) style intake inlets
* Trick Flow's patented Fast as Cast intake/exhaust ports that deliver near CNC-ported airflow
* Fully CNC-profiled combustion chambers
* Bulletproof 3/4 in. thick decks
* 4-bolt replaceable cam bearing journals
* Full 3/4 in. reach spark plugs (no more blowouts or inserts!)
* Stainless steel 1.840 in./1.450 in. valves
* Trick-Alloy powdered metal valve guides
* Ductile iron valve seats
* Lightweight chromoly retainers and locks
* Die-forged locks
* Dual valve springs good for cams up to .600 in. lift
* Viton® fluoroelastomer valve seals
