225-231-252 V6 Aluminum Heads In continuation of pushing the performance envelope of the Turbo V6, we have developed a line of aluminum cylinder heads for street and/or race. Available in two versions, both of these heads were designed to out perform previously available heads both in power and quality. Improvements in all areas have been made to increase flow, strength, durability, serviceability and valve train alignment. Painstaking detail has been applied to ensure that pushrods will clear with any rocker combination. Both have provisions for 14 head bolts, however, they work equally well with production 8 or 14 bolt blocks. Runner CCs Int./Exh. Chamber CCs CFM (max) Int./Exh. CFM (base) Int./Exh. Valves Int./Exh.

Amount of boost, fuel and degree of tuning are the major factors. Optional 1.940 or 2.020 Intake valves available. Must chamfer bore on 3.8 blocks for 2.020 With 2.020 Intake valve and FULL porting Assembled heads include standard valves, springs, keepers, retainers. 3 3 3 4 5 5 4 4 3 Other areas of improvement/refinement include: - a raised valve cover rail which allows better clearance for roller rockers with OE valve covers. This enhancement also reduces the chance of oil running down the side of the head when the valve covers are removed. - all threads are rolled, were as a conventional tap cuts the metal, the roll taps used with our heads form the thread which results in a stronger thread due to hardening of the aluminum during this process. Ideal for header and valve cover bolt locations! Street Intimidator Our entry level head, requires the least investment in order to upgrade to aluminum heads. Provides considerable performance gain right out of the box or can be upgraded and ported for more serious combinations. The SI head can use Stock Rockers or TA V1309SI Series roller rockers. Rocker ratios of 1.55 to 1.65 can be used without any pushrod to head interference. Street Eliminator Our high performance head. Versions of this head with big valves and heavy porting have made 1500 hp on a 274 inch twin turbo application.Use this head for serious street/strip and race applications, where the most power potential is desired. Requires TA V1308 series pedestal type roller rockers. Works with rocker ratios from 1.55 to 1.75 with no pushrod to head clearance issues. Added material for greater strength Part Nos.
