Adding 2.02 intake to J heads

I picked up a little time and speed with the 1.88 - 2.02 swap, BUT! This may not be true for you. It is application dependent as well as build dependent. My car was a 4spd & 4.10's at the track. The gain was small. It was a very long time ago. Those details are lost in time.

If your valve is high, I wouldn't waste the time on 2.02's on a street ride.
