Highest flowing sbm heads?

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!

My pistons were always going to cost 1000, I'm not using the victor, I have a ritter block already, 1300 for headers is only 200 more. Is there another head option that performs as well that is cheaper than Victors that I missed? I did ask if there was another option.
