    The double hump fueler heads have bigger intake valves, but the L-31 cast iron Vortec heads have better port design (flow more) & they also have the fast burn combustion chamber design, so like Blacksheep said, it kind of depends on what else you've done to your engine. The cast iron L-31 Vortecs (pn#12558060) with compatable valves, flow more air than the Phase 2 Bow Tie heads (pn#10134392) as per GMs' Performance Division gurus.
