what kind of hp difference between heads?

Agreed!!!!!! Brian ports then REAL nice!!!!! I think your right,I think its more like $1,300
How do I get in touch w/ Brian? Are these 202s? Im interested in a set. $1300 for heads that flow that good seems fair. They definately dont flow .280 out of the box, and port work is not cheap. Want a set for my stroked 340. .030 over w the scat 3.58 stroke crank. Thinking comp 282 solid cam.
