360 heads on a LA 318 vs Magnum heads on a LA 318
water crossover instead of exhaust crossover so you don't end up with a couple of lower flowing exhaust ports, chambers cc'd at 62cc after a bit of de-shrouding around the valves and stock style valves with the dimples in the face. Aftermarket flat faced valves would get you to about 60cc I reckon. Not bad heads really but port volume was smaller than a standard 675 head.
Don't forget the industrial stuff!
