High CFM heads - What would you chose?
Rob I don't have many photos, just didn't think about taking many. I was concentrating on fitting and assembling everything.
The intake ports are 230cc, exhaust 87cc and the chambers are 70cc. The heads were flowed using a 4.030" test stand. My engine is 4.090" bore. My porter said he went conservative because of the known porosity issues with these Indy heads. I'd rather give up a little air flow and not have a set of expensive door stop.
Intake, .100" 65, .200" 115, .300" 166, .400" 220, .500" 271, .600" 308, .700" 310.
Ex., .100" 62, .200" 82, .300" 126, .400" 156, .500" 180, .600" 197, .700" 208.
