Gen 4 heads on Gen 3?

[YLW DRM2]

Will I gain HP by putting Gen 4 heads to the Gen 3 and recalibrating the CPU? Can this be done as a simple bolts on?

You would need the whole conversion kit from Arrow racing with a front cover etc.

hehhehe Not a simple bolt on. Yes you will gain a lot of power but again not a simple bolt on.

Are they that much cheaper than Stryker heads?

How much of a gain, and how much $$$ ?

Arrrow was quoting 80 to 100 rwhp with a midified cam.

Not a simple swap, but doable. The problem is that you will be over 8K easy in parts because you need the manifolds, valve covers, coils, etc to work with those heads. When the market for used Gen-4 parts stabilizes a bit, it may be more worthwhile, since a Gen-4 engine right now in good running shape will pull 12-14K pretty easily. However, depending on what you are doing, it may be more worthwhile than Strikers based on the manifold changes alone.
