Stage 2 SC porting consist of bowls reworked and short
turn radius recontoured on the intake & exhaust sides.
Both the intake and exhaust runners receive full porting
& polishing plus the center intake runner is reworked.
The chambers receive taller over size valve seats and are
reworked to promote low lift valve flow & minimize
valve shrouding. The chambers are then highly polished to
help retain heat. CMRE valve seats are formed on a Winona
CMC 30 cylinder head machining center with 3 angles and
two radius, with seat run out .00 I or less, the valve
seat heights are equalized to .002 and are fully blended.
The valves are reworked to complement our seat design, as
they too play a big part in air flow. All valve jobs are
vacuum tested. Stage 2 S.C. heads are flow tested on our
SuperFlow 600 computerized flow bench at 28" H20 to
ensure that your heads are as good as the ones we bolt on
our 425 plus HP stage 2 S.C. engines.
