914 rebuild

Engine

Vehicle Information: Model (914/4, 914/6): 914/4; Year: 1972; Engine (type, size, modifications): 2.0; Total Mileage: ?;

I've got a '72 914 with a '73 2.0L engine/transmission, and a 911 front suspension. I am getting ready to do a rebuild. I had the heads redone about 15,000 miles ago, when a valve seat came loose and caused the valve to stick open and bang a dent in the piston. I am finally getting ready to replace the damaged pistons/cylinders. Since the car is not original, I am not concerned with SCCA/autocross rules, and am interested in any modifications that would improve the power. I currently have Euro pistons. However, I notice there are serveral big bore kits out there. Are these worth a look? What would I have to modify on the fuel injection to deal with the extra displacement (increase fuel pressure, adjust pressure sensor, richen fuel mixture on brain box)? Also, do you recommend hydraulic cams, or high volume oil pumps?
