I am in the process of putting new gaskets from the head up on my engine, and I'm doing some performance upgrades at the same time. I have an underdrive pulley, aftermarket intake manifold, header, and intake already. I'm thinking of getting a cam gear and a camshaft from a SOHC ZC to swap in. Would these two parts be worth getting or would the gains be minimal? Also, could a novice install both of these? I've never messed with the internals of an engine before. Thanks.
