At the 2007 ARRC, first gen Honda CRX's finished one-two-three.
First place had an original Honda carb, and new lap record. Runs so good it can be driven on the street.
Second place car had a 32/36 Weber, and time just a small fraction slower.
Not sure what Jinx was running in third place car.

I agree with the poster above that head prep is most important, but the cars in first and second place at the ARRC didn't find the use of new rockers necessary. If they are still in spec, run them.
