After 15 years of development the latest "590" Series alloy VN style heads for the Holden V8 are the best Street/Strip power makers available anywhere.

These heads flow over 590hp out of the box with a small 182cc port volume intake runner and should be a persons first choice for any engine combination to around the 400-500bhp mark in a street or street/strip engine.

Producing incredible torque and response particularly in the smaller 5 litre or 355ci

Stroker engines you cannot buy a better cylinder head anywhere or even attempt to modify a factory cast iron head to produce similar results for the cost of our 590 heads.

With a 22kg weight saving. A fully developed unique combustion chamber design. Fully machined to accept any aftermarket 7/16" stud or shaft mount roller rockers.

Heads are supplied with our own proprietary 1.450" diameter dual coli valve springs and chrome moly retainers, positive valve stem oil seals, valve locks, Springs will work with any flat tappet or hydraulic roller cam profiles. Specify cam specs at time of order and we will match springs to suit.

Stainless steel 2.02" intake and 1.6" exhaust valves. Hard stellite valve seats for use with any fuels. Solid bronze valve guides.

Port placement is standard GMH which allows any aftermarket or factory intakes and exhaust manifolds/extractors to bolt right on.

The same applies to accessory mounting for air-con, power steering and alternators. The heads are a direct repalcement in this regard.

Fully re-designed water jackets provide improved cylinder to cylinder cooling consistency and the chambers allow large increases in compression ratio possibilities without detonation on pump fuels.
