The basic machining is being done at Eliminator Products and can be finished at Barnett High Performance or any other machine shop that know how to machine blank raw heads.

It takes around 2 weeks to machine and assemble these heads depending on our work load.

Port flow out of complete heads from Barnett with 2.25 intake 1.76 exhaust valves
with our valve job and blend

Assembled by BHP intake flow 350cfm @.600 and 390cfm @.900 with 2.25 valve
Assembled by BHP exhaust flow 230cfm @ .600 and 275cfm @.900 with 1.76 valve

These prove to be the highest flowing factory valve angle 460 heads made.
