Aluminum cylinder heads

We want to go with a set of aluminum heads on our 72 Swinger w/383 and auto trans. Right now with the iron heads and Schumacher headers, the plugs are a pain to change and the plug wires are very close to the headers. We're looking at Edelbrock E-Street 75cc angle plug heads. Is anyone else using this combination? What are the pros/cons?
Thanks

Double check what your compression ratio will be with the 75cc chambers. If it is okay then you should be fine. Those will be nice heads for your application. I wouldn't use the E street head if I was trying to build a performance engine but sounds like you just have a basic street car so they should work great.
