Just curious what people have. What do your heads flow? What kind of heads? What kind of work done to them? What's the motor combo and how much HP?

440-1 heads originally ported by Radar at R & J from Cedarfalls Iowa. VERY pleased with the power they made originally, but got greedy and tried to improve on the original work with 2.3 valves. Of the two plots on the chart, the lower flow plot was with 2.25 valves, one with 2.30 valves and exhaust reduced to 1.78 to make room for them. Didn't show a bit of power improvement with the bigger valves, so I may send them back to R & J and see what they can do, if anything to make use of the extra flow.

Mine on 2 different benches, one was Modern Cylinder Head and the other was Dwayne Porter. Modern flowed the exhaust with a tube where Dwayne did not, that is why the ex numbers vary. Heads are Indy -1's that were hand ported by Barton. Motor made 850ish HP and is 557 cubes. Pushed my car to 9.ohs and a couple of 8 sec passes at 3000 lbs.

We're around 380 cfm @ 700 hand ported but this is on a kit type, self assembly bench (can't remember the manufacturer ) Motor makes around 850 hp, runs mid 9's @ 3850lb (W/D) so figures are probably near.
