I will have to disagree with the above. If you put a b16 head on the b18 ls block you get a compression boost. The b18c1 head is built stronger but the b16 head with upgraded internals is by far more powerful. With the b16 head u need to make sure ur internals have been upgraded and make sure to get some better head bolts so it dont lift on u. But if u just want to slap vtec on it and be done with it go with the b18c1 head. And if u do that do your self a favor and get a good intake manifold. (personally i dont like the stck gsr manifold ur choice tho)
