318 La with 360 heads

I always chuckle at these 'big chamber heads on small bore'' threads. You can make power with bigger valves and ports but at the expense of a bigger open chamber and a loss of compression. You can put bigger valves and enlarge the chambers of a 318 head to almost equal the 360 head or you can mill the large chambers off to 318 size. Lots of material. Probably .060 or more) If I was to just "swap heads" on a 318 to gain horsepower, I would go 920's, 302's or Magnum if I wanted to loose the open chambers and increase compression. Aluminum's to increase flow If porting wasn't happening. There is no perfect answer, no magic bullet!
