What is the best head for a small block.

2400lbs with a 408. Prostreet with some racing. 14x32 tire backhalfed 904 trans

At that weight anything will run 10.90’s.
Out of the box eddie heads on a 360 will run that good at that easily.
I have a 10 to 1 bone stock 360 shortblock with cam and boltons and have been 11.20’s already at 3300 pounds. Mildly worked eddies
Hang around till the end of the season and i will sell the motor complete carb to pan. In your car it would go mid 10’s easy.
