Highest flowing sbm heads?

Well so far the only hassle is the exhaust, steering. The rockers I think I have figured out and that's reasonable and there are no comparable heads to consider. So I don't see this as being more expensive yet.

You’re going to have 1300 in headers, 4100 in heads, another probably close to 1000 in a ported super victor, and 1000-1200 bucks in a custom 16 degree piston.
Guess it isn’t all that bad. Doubt I would run that head on a stock block, if having the block. live any appreciable time is a consideration.
Should be fun!
