Who's 440 heads flow the best?

Ask anyone and you'll find that everybody is better'n anybody else!

We suck at porting. Everything we do is by hand and it cost more than any CNC program.

We can't get any more than 620 HP horsepower out of an Indy LAX headed 424"/360 pump gas small block, 787 HP out of Edelbrock RPM heads on a pump gas 451, 928 HP out of Victor heads on an E85 500"/440 and 748 HP from factory 906 heads on a pump gas 500"/440.
