HOLDEN Grey Motor Cylinder Heads
$2,200
These heads are an excellent upgrade for your mighty little grey motor and will be capable of anything you throw at it with quite a few of these heads being on some quite respectable street and race cars.
They handle any solid flat tappet camshaft you can fit in a grey, and although the ports look big they are no bigger than the locator rings in a factory head so your manifolds will all work with it (we can also dowel your manifold if you bring it in) and if you want more there is still lots of room for improvement and bringing the flow up from 165hp to 195hp if required
The Fully 6 Grey follows the same recipe we use for all the inline 6 holden heads we produce.
Oversize custom profiled valves,
Reconditioned head (chemically cleaned, pressure tested, new guides, inserts suit unleaded, surfaced to min volume)
Bored out intake throat, enlarged bowls and ported (to flow around 165hp @.500" stock is about 120)
All new parts, double springs, chromoly retainers, hardened machined locks and viton stem seals.
We prefer to use your own heads with grey motors as stocks are really low as everyone knows how hard it is to find non cracked and usable heads
