305HO Heads on 307
I believe I read on here (or maybe on a chevelle forum) that mid 80's 305HO heads(14014416) would be a big improvement on a stock 307. It's time for a carb and I'm just trying to decide if I want to swap out the heads while I'm at it. I plan on keeping the ram horn manifolds. Exhaust is 2" dual currently. Any experience with the 305HO heads on a low-hp engine?
