but again, the point is there are options on the heads that aren't a bajillion dollars that will still make decent power.
this setup is a great piece because it's totally malleable. add roller rockers, sure! here's 10hp. add a carb spacer and double pumper? why not! here's another 10hp! tweak the cam, pick up some torque and maybe another 5hp. go nuts on the heads? okay here's another xx hp.
