If i buy a quad 4 LO, would i just need to swap the head to make it a HO?
"The powerplant is a 2.3L quad 4 motor. It is a DOHC 4 cyl, producing approx. 150 hp in its current trim. This is, unfortunately, the Low Output version of this engine. I'm trying to find an HO (High Output) head to put on it for a low price. But even the LO version of this motor is better than my old Duke. Despite it's lower displacement, it produces almost twice as much power as the duke, due to its higher revs, and 4 valves per cylinder."
This led me to wonder about the head swap, i took it from this site..

I am asking because it's alot cheaper to get a full car with an LO.
thx
