Don't know if it true but heard that newer 3800 L67 heads are better than the LC2's any flow data or truth to back this up? Can they bolt up to a 109?
 
Stock they flow better. The only dimension the two engines share is that they are both 90* v6's, there displacement and the rod bearings. Totally different engines.
