AFR heads tend to not need the extra exhaust duration. It will work fine or possibly a straight 1.5 exh rocker. The 227AFR is a good piece and even though a little small for a 421>7000rpms they are still gonna work fine. If your running alky then its a whole new deal.

There is not going to be anything lazy about it!!! But will run out of air quickly after peak.
