Re: Another head poll
i don't know why you wouldn't go with the vortec. I have vortec 906 castings (not installed yet, engine swap still in progress). Vortec will give you the best flow out of the box, no porting necessary. Vortec = proven power. 305 heads on a 350 is not a good idea anyway. They are not made to accomodate the larger displacement.
