Alloy Heads

Thanks for that Evil. I'm trying to keep it looking stock under the bonnet. Did you have to do anything to get them to fit or was it a straight bolt on ?
I got an email back from Aeroflow yesterday. This what they said.

Here are the specs for the Aeroflow SB Chrysler cylinder heads

installed height 1.8"
120 lbs installed pressure maximum lift .580" 1.46" O.D open pressure 320lbs @ .580" 2.02" intake valve size
1.6" exhaust valve size
176cc intake runner
75cc chamber size

intake flow specs
.200" .300" .400" .500" .600" 129 190 231 249 251

exhaust flow specs
.200" .300" .400" .500" .600" 108 144 170 183 190

Look pretty close to the Edelbrock heads from what I can see, but over $1000 cheaper.
