It's the 4.50" bore. I asked about Edelbrock heads and was told the chamber was larger in diameter. So intake valve might nick the edge bore. It's like Max Wedge 1.88" exhaust valves. What about Indy Heads? Read a member dropped a seat, this a one off or a habit.I have Mopar Performance heads cast by Edelbrock. Basically the same heads. I run them on my 528. However, it is a 4.503 bore. I also have larger Manley 2.500 int and Ferrea 1.990 exh valves.
I assume you are talking about Victor Jrs. You have to say that because Edelbrock also made the last of the Mopar aluminum heads which are basically street hemi heads cast from aluminum. The Victor Jrs are the best deal in Hemi heads. Anything else is........well, just don't think about anything else.Has anyone run the Aluminum Edelbrock gen II HEMI heads? If so what valves are they using and are they worth running?
