Going to ditch the Iron Heads and Pick up a set of Brodix Race Rite Series Aluminum heads.
Wondering if I should go with the 294cc or the 312cc intake runners? "will most likely be building a bigger motor once this one goes"
Also I have 109cc closed chamber 291 heads on there now and the heads I'm getting have a choice of 115cc or 119cc chambers.
What will the difference in compression be and will it be noticeable at all?
Motor is a twin turbo 468
Single boost referenced 850 with a lot of work done to it at the carb shop
