Ported cylinder heads - brand new
 

For Sale a pair of new cylinder heads - NOW SOLD

$1050 + shipping

the heads have been ported to a 'stage 1' effect, so sharp edges and casting marks have been removed and the valve seats blended into the port to remove the step
the combustion chamber has also had sharp edges removed to help prevent pre-ignition and the valve areas de-shrouded as much as possible
I've shown a before and after image of the combustion chamber - but all chambers will be ported

The valves are standard but brand new and are built up with stronger springs ( kelford cams items) as the stock items are quite weak and allow valve float at 7500rpm
these new items are suitable for 1.2 bar of boost and 8000rpm, so good for a turbo / forced induction build
the uprated springs are on both inlet and exhaust
same as sold here

Will there be any gains with this? Smoother torque line? What kind of changes can be expected? Based off stock motor.
