PI Head Swap

Which would improve the most on the 1/4 mile run?? The PI head swap or 3.73's??

When you say PI headswap, I'm assuming you mean all the other necessary (or complimentary) stuff that goes along with it? If so, then of course the PI swap would be more beneficial. But again, you're probably going to spend 5 times the cost of gears and install to bolt PI heads to your motor. I don't know if that's a fair comparison, but it's a comparison nonetheless.

The PI headswap will be alot more beneficial of course but,
will cost alot more than doing gears.
