Will the cam advancement change between the 270 and 280 degree duration?

Given the motor specs, Would you lean towards one or the other?

I would assume that the 280 would be on the safer side of things but less bottom end.

Setting up a stock efi motor to run on 91 octane

What if you were to take a stock efi 300, and put flat top pistons in to raise the compression up to the 9.2 ish range? Or a level safe for 91 octane.

Would this have similar results to putting a smaller cam in that raises the dynamic compression?

So can you put a larger valve in an efi head and maintain the fast burn quality? If you only pushed the shoulder back the amount the valve increase? Or would a larger valve drop the velocity enough to compromise the whole swirl effect?
