Extra Notes:
The street heat intake has 15 inch runners and the track heat intake has 12 inch runners.
The street heat heads come with smog provisions and the track heat does not. The track heat heads can be ported a bit more because of this.
Both the street heat and track heat heads come with 3/8” rocker studs and the track heat heads can be upgraded to thicker 7/16” rocker studs. Just call your sales representative to get the upgrade.
Both street heat and track heat versions have the option to come with dual valve springs and 10* locks.
Twisted Wedge and Street Heat Heads are the same, not to be confused with Track Heat.
The trickflow h/c/i packages are more designed for the fox-body cars do to valve cover tallness and throttle body adapter plate not being included.

I'm with Grady, it looks like the Stage 1 cam's powerband starts a little bit earlier compared to the Steeda #19. The Steeda #19 could possibly idle a bit better, but nothing a tune can not take care of
