Highest flowing sbm heads?

And for those that have question the "cost" of the 485 "net hp" 6.4, I went on market place and found one all complete for 700 bucks. Has warranty as well.

Thats cool. Third gen Hemis are good motor but not without their problems. Plus its cheap to buy maybe but by the time you spend all the money to get working in a car. You could have pit a hot small block together. This thread is about a 59 degree small block and what head to use. So this isn’t really pertinent or helpful.
