He should be buying a set of roller rockers no matter head he gets but these heads will accept stock rockers. Stock valve covers can be easily grinded down to clear them. The exact same things needed to bolt on Tumpers are needed for these heads nothing more!
Yes morales those are the heads, they are far superior to the ported stokers and as I stated will out perform them all day long.
No RRs are not needed for the thumpers, they do not need the same things, you can use stock rockers and it would be fine, you dont gain much with RRs unless you increase the ratio to 1.7 or more.
