Sportsman Ported 3500 Cylinder Heads

Product Information

Only available from 2004-2006, these non VVT heads are a huge step forward for what is likely the last revision compatible with the 3400 engine. These will not fit the 2.8, 3.1, or 3100 engines due to the combustion chamber size vs the bore of the engine. 

 These cylinder heads are our answer those looking for  high performance at the lowest cost possible.  All expense is spared, with only the necessary modification done to the intake, and exhaust ports  Priced as bare cylinder heads. Stock valves, springs, retainers/keepers, and new seats/ seals are included.  Stock valves are cleaned/blasted and the seats reground when necessary.  Valvetrain upgrades, milling, and valve job are all optional.  All options that require extra work (i.e. PAC 1518 springs require spring pocket machining) is included at the listed price.

• LX9 3500 cylinder heads
• Cleaned, inspected, and glass beaded.  All threads are plugged prior to blasting, so easy installation is assured
• Street/Strip carbide porting on Intake and Exhaust. 
• Valves lapped
• Deck surface free of all gasket material and cleaned
