Head Details


S&S Street Eliminator Head

This is the first step in the line of T-Man Performance heads using S&S head castings. This head comes with a custom 2.020 intake and 1.610 exhaust valve and features a 1.800 inlet opening. The heads features fully CNC ported intake and exhaust ports, and a radiused chamber to control consistency from head to head. All machined areas are hand finished to insure max flow and port velocity.

Head packages require your heads to be sent to T-Man Performance for work to be completed.
* When not using T-Man Performance pistons the builder is responsible for checking all valve to piston clearances.
** Due to the amount of material machined off of the surface, the manifold fitment will need to be checked.
  (T-Man Performance offers a machining process for the manifold for an additional charge – call for details)
