Heads

Good morning all I'm looking to replace my heads and would like to hear from you guys on this matter. I have a set of eddy heads on my stroked 340(416) It runs good but not good enough. Im looking at the indy set up 360-H1-1K or the brodix set up the car goes 11.40 now and is a street car would love to get into the 10's. thanks for any advice
