HEAD COMPARISON CHART

Here's a site comparing heads. Good for bench racing at least.

Looking at that chart is very interesting but one thing to bear in mind is that the HP numbers are the MAXIMUM possible with optimum settings. ie: optimum fuel, timing, compression ratio and minimal restrictions upstream of intake port and downstream of exhaust port.
An intake manifold, for example, and its runners represent a significant restriction in airflow as does a carburettor -no matter how big.

And don't even go to places like valve bounce, misfires, timing accuracy, the list is endless and each and every factor can have a noticable effect on power production.

Yes, I know that they have three different formulae for various types of engine but still it may be as well to bear that in mind.

So, as they say, results may vary -particularly on a street/strip engine on pump gas.
it'll be interesting to see what the real world numbers are on the GM (aaaargh...!!) BB I'm currently assembling with loving care. I ported and cc'd the heads and then put them on the flowbench. The raw numbers were comparable to those quoted on the chart and those numbers extrapolated to roughly those quoted -albeit that my camshaft will be slightly more stout.

Time will tell...........

My current heads flow 430+ at .750 lift on int and about 400+ at 750 lift on ex. I have over 5000++ in them w/o valves springs or retainers.

If you want performance go aluminum, and after market...

Race Wedge guys use Predators, B-1 etc Hemi guys use Stag V Brad Veney, SS guys/ low dollar budget guys use the 440 source guy Brandons stuff.
