Is there enough of a difference to make it worth swapping on a 306 with Windsor Sr. iron heads,  an e-303 cam, a t-5 and 4.11 gears?

Air Gap 351W is slightly larger, and much taller than the regular RPM.
Air Gap 302W is the same size inside, and the same height as the regular RPM.

For a 302, save your money. 

Good Luck!

It will make no measurable difference on the 302 based engines.  I have seen articles where the Windsor version picked up a couple horsepower with the swap - but if I already had a regular RPM i wouldn't spend the money swapping over with the 9.5 either.

I'd rather be a fool who is loyal to his friends than a POS that jumps ship to save face. We were wrong in the end, but nobody can ever call us disloyal. I can live with that.
