Stop in for a cup of coffee

Good morning, Ray and Mike!

Just dropped off my Holley 600 and an Edelbrock air cleaner at the "post office". Got $250 for a $53 carb and the air cleaner that came with my car. Now I'm on the hunt for a pair of high-comp heads.

What would you guys suggest? 318 closed chamber heads?

The early heads from 66 or 67. The 67 heads end with the number 920 and are closed chambered...
