Let's see, Unported Speedmasters out of the box to CNC Ported Trick Flows. The Speedmasters are 1 small step better than OOTB Edelbrock's and ported Trick flows are a step away from W2's. They better give you 50 horsepower on an engine like that.
Mmmm since the TrickFlow heads are ported we gotta compare them to ported W2 heads. And that’s no comparison as the W2 heads would kick the TrickFlow heads butt.
