hughes rockers / shafts

Can I use my old oem 360 rocker shafts with the new hughes 1.6 rockers?

They sell the new groovy shafts for what looks like an additional 100.00.

Are new 100.00 shafts a fat waste of $ ?

If I understand the advertisement correctly.....450.00 for the hughes w/ new shafts.

Thanks.
