Street 3500 Cylinder Heads

Street 3500 Cylinder Heads

Product Information

Best for street oriented builds, with 6k rpm or less in mind.  Stock valves, retainers, and keepers are used along with LS6 springs, new valve stem seals, and modified LS1 valve spring seats. These WOT-Tech Street 3500 Heads are great for the stock camshaft, or one of our .510" lift or less performance cams. 

Flowbench tested and proven, these heads offer the performance and fuel efficiency of any 3500 heads you will find anywhere.

Manley Steel or Titanium retainers are available as well with these heads (Manley steel keepers included).  While not necessary, the Manley parts are exceptional quality.
