Thanks for sharing the pics of the heads, we are a bunch of doubting Thomas's when it comes to making real power with these. Giant ports aren't always the answer as port velocities slow waay down resulting in poor air/exhaust flow. Same holds true to huge valves. BTDT years ago. 8000 rpms is great but what about hp the rest of the rpm range?
