Which heads, any gains ??? Im currently using a pair of Edelbrock 215cc heads, as CNC'd by West Coast racing.
flow data here.
I was having a nosey over in the other sections and seen Trickflow's offerings.

Obviously at 382ci, I'm on stock bore size. My cam lift is circa 590/580 in/Ex
Would upgrading to different heads, offer worthwhile benefits ??
Cost is an issue, but I should be able to sell my current Edelbrock units ok.
