Highest flowing sbm heads?

I would not go crazy with the Harland Sharp rockers. While you can make some nice “Street, strip strip” power without a big worry, there not for swing for the fence with. I have some Econo heads that will get the HS rockers for a nice street build. Nothing to hairy. Just a solid cam with a reasonable lift.

As mentioned before, Jesel or TD rockers are what you want/need. I’ll be down for two sets myself.
