I strongly disagree with the last 2. Don't reduce the floors on the intake side. The intake side on a 1g head flows so freely that all you have to do is clean up the casting flaws and do a little port matching. The bowls are also very good from the factory. Most people mess those up when they are trying to do good. The big place to gain HP is on the exhaust side of the head. The runners can be opened up a lot and the dividers thinned down.
