COME Racing Alloy head range expands  
In these tough times we are spending enormous time and effort in the development of new and improved versions of all our products. Our latest 2009 VN Holden V8 alloy heads are just the tip of the iceberg. These heads are the FIRST and only Holden V8 heads on the market to be a true out of the box bolt on power maker with ZERO porting required for engines up to at least 550bhp. Bottom line, bolt these $3500.00 per pair complete heads on your street or strip Holden V8 and they are equally at home on a mild 380bhp daily driver 355 or a Bracket Race 383/396 stroker making over 550bhp.
With small 182cc intake runner volumes for incredible air speed and over 570bhp potential through these small high velocity runners you will always make the best possible power and torque compared to fully ported cast iron heads and any other alloy heads on the market today. This is a simple fact of life and most importantly the cost is actually lower per cfm of airflow than anything on the market today. We realise traditional head porters are not happy because they are no longer needed to modify factory or other aftermarket heads for you to make maximum power.
To that end however, we have also catered for the higher power level applications right up to full race engine needs in a new collaborative effort with renowned 5 axis computer numerical control cylinder head porting company Bullet Cylinder Heads in Adelaide http://www.bulletcylinderheads.com.au/ They have developed some incredible automatic machine ported combinations using our latest 2009 castings. For those of you wanting to maximise results with primarily big capacity engines or race applications Bullets fully machine ported heads will outflow anything else on the market by a large margin.
The Bullet computer ported COME 2009 heads are available direct from Bullet or from COME Racing. Making big power from your Holden V8 has never been easier with parts you can take out of the box and bolt together.
For example...take our 355 forged piston Stroker kit, our out of the box UNPORTED 2009 alloy heads complete and our COME Racing Twin Throttle Body intake. Use one of our hydraulic flat tappet streetable cam profiles and you have a genuine 450bhp easily. Want to go bigger, the same applies to our 383 and 396 versions which make insane torque as well as power. 500+bhp in fairly streetable engines is now very straightforward.
You want to race more than street drive? Add our new 2009 Computer ported street heads to a 383 or 396 engine and make 550+ bhp with absolute ease on pump 98 octane fuel. A complete pair of these computer ported heads which flow over 640bhp are $5500.00 per pair including full valve seat job, dual flat tappet 1.450" springs, moly retainers and locks, positive stem seals, solid bronze valve guides, Ferrea stainless steel extra length 2.08" intake and 1.60" exhaust valves.
Remember also our NEW Holden VN V8 style single plane single 4 barrel carb intake manifold will be available very soon to totally rewrite the power potential of carbed combinations of the big cubic inch Holden V8's. We will now have you covered for EFI or carb intake. You all know the reputation of our EFI manifold. The new carb intake will provide the same boost to carbed combinations as the sorely needed EFI version did all those years ago. A new level of performance has been needed for the carb intake for many years, it will soon be here.
Remember also...COME Racing heads are fully designed, developed and manufactured right here in Australia. The quality of materials and machining is second to none so if you are tempted to look at the junk coming from Asia we suggest you spend more on the local product because in the long run our local product will actually prove to be the lower cost alternative. Don't just think with your hip pocket nerve, it will bite you when you realise you have bought an inferior product that cannot produce the results of ours no matter what you are told.
