Lawsuit anyone?
45cfm @ .100 lift ..where STOCK sbm will do 60's cfm and 10-15 lower than stock up the scale.
They actually measure as follows..
Intake port 150cc
Exhaust port 60cc
Chamber cc 62cc
Once you turn them into something decent ..
Int 160cc
Exh 64
Chamber 66cc- after digging up the valve job. Stones and hand blending.
They are getting a premium for some strange stock looking non eq/rhs heads and people are getting screwed.
Most people would get raped if they put these in a shop let's just say ...
They sell their aluminum head that flows way better for a hundred and something less. Which by the way is another case of false advertisement because they advertise that head with a three angle valve job and it is not a three angle valve job. Speedmaster is pissin in their own tea.
They flow like a coffee straw till .450-.500 and not great.
