More boost alone will not nessarly make more power if you don't have enough fuel to go with it, this becomes the biggest problem how to get enough fuel to keep the engine from detonation and melting parts.
With siamesed bump ports, to get better air flow, the easy way is to use fuel injection with methanol it can be run extermely rich, almost like a Top Fuel car, the cylinders run cooler won't lean out as easy and melt parts. otherwise keep under 400 HP
With the 12 port Sissel Kirby head (the best flow )you can you can make more power with an intercooled, injected or carb set up on gas.
