I am planning my next engine build. It will be a 512 stroker using a 400 block. I have a set of Indy EZ heads. I've had them about 10 years (bought new and never installed on an engine). Are the Indy EZ heads from that era taller than an Edlebrock head? This engine is going in a 68 Charger/Auto and I want to use the stock hood. Also, whats your opinion on these older heads? Would they be as good as a modern Eddy or 440 Source head?? Thanks
