105's and a stock timing chain is more than adequate for either of these cams.
But if you do decide to get 130's, a double roller would be a good idea. Just know a lot of work goes with a double roller (machine oil pump cover, machined crank gear).
what if i DO want to rev to the moon? do i get 130's and the double roller chain?
