what is better for drag racing?
oval port heads or rectangular on a big block 454
Depends on the combo. If your spinning High RPM as in over 6000 a Rectangle will be better for you. If its a streetcar and see down low alot a oval will be better. Some will argue but a oval is a better "street" head to have.
