I recently saw that aluminum heads are being sold by 440source.com for a pretty reasonable price. It looks like they will be really good heads for the price, which opens it up as a possibility for me. Yet, I've got some concerns with compression and such. I currently run 346 style heads on my 440, which I think is a 76 cc chamber. Fellow Mopar guys tell me if I'm wrong. Anyway my current compression is about
9.5:1. These heads come out standard at 84 cc, what am I going to lose in compression? Is the trade off worth it?
