Given the Combo, use the 1.7s and the stock cam:bigthumbsup

Get the cam since your engine is already going to be apart. That way you don't have to do the work twice.

Ok
1) Performance- 1.72 gives u a .472 lift that's near the GT40's peak flow of .500 more lift won't help.
2) Drivable- its a stock cam, they have been driven for over 200,000, so ya that's covered.
3) Sound- well its stock so not really a "good" sounding cam
4) Streatable- refer to # 2
5) Price- u have the stock cam so its free, new the frpp RR are like 200??? Used 100-130? Just depends.
6) RPM Range- well again stock so done by 6000 with the improved flow

Sorry, all ur stock valve train will work with 1.72's.

I think that for ur money the 1.72's would be best unless ur looking for the sound then a cam would be better.

What are u goals or future plans for the car?

Go with the stock camshaft and 1.72 rockers for overall driveability and power. The E-303 cam is a piece of junk, its a magazine queen.

With 6pounds later I would deff. Go with the stock cam and some 1.72's.all alphabit cams are old and out dated.
