911 1973 1/2 2.7L Rebuild Options

Engine

Vehicle Information: Model: 911T; Year: 1973; Body Type: Coupe; Engine (type, size, modifications): 2.4L bored to 2.7L; Total Mileage: 125000;

I'm in the planning stage of rebuilding an old friend who blew an exhaust valve during an autocross nearly six years ago. Let's just say that THIRD gear, not first gear way my intention...The case has been opened up from the original 2.4L to a 2.7L; I need some advice on my choice of options. Although it's not the optimal setup, I plan to keep the CIS injection system intact. So my two major questions revolve around piston choice and camshaft options.Wayne Dempsey's book "How to Rebuild & Modify Porsche 911 Engines" specs out a 2.7L engine with JE Pistons (90mm), 2.7L Nikasil cylinders, and 964 camshafts. Is this a viable option to get the most out of this CIS-based system and still remain reliable? And, if I choose to convert to carbs/MFI and S-spec cams in the future, will these pistons be appropriate?I'm just looking for some advice before going too far in the wrong direction.Thanks for your time.
