I posted photos quite a while back of our development 5.0L head and our stage 1 head is now ready for release. We are currently working on stage 2 and stage 3 heads, which will be a separate port design and include upgraded hardware and be available shortly.

All of our cylinder head development, flow work, and cnc machining is done in-house at our Dearborn Heights facility.

Cores are not readily available at this point, so a customer supplied head would be required. They can be sent fully assembled or disassembled.

A) Customer supplied heads sent bare and clean - $899.00/pr. + shipping.
CNC ONLY (for optimum flow, we highly recommend a valve job and custom ground valves). For an additional $100.00, we can disassemble and return to customer bare with all associated parts.

B) Customer supplied heads sent fully assembled or bare (with all associated parts) - $1,299.00/pr. + shipping.

  • 5 axis CNC machining
  • Custom CNC valve job
  • Custom ground factory intake valves
  • Custom ground factory exhaust valves
  • OEM valve seals, locks, retainers, and valve springs
  • Cleaned and assembled w/o camshafts

Thank you

These heads are currently on our automatic shop car. At the time they were installed, we also raised compression 3/4 of a point to 12:1.

We saw gains of 41 RWHP. Existing mods were Stainless Works Longtube Headers, Stainless Works Catted Mid-Pipe, Stainless Works Catback, Steeda CAI, 1-Piece Aluminum Driveshaft, Livernois Motorsports Dyno Tune. We then tried a different intake manifold and picked up another 10 RWHP.

We plan to do engine dyno testing with a stock engine as soon as the other heads stages are complete. On a stock car, I'd say 30+ RWHP.

Thank you
