I have 2 sets of EAB heads, both are pretty nice. The orange set is really nice in the combustion chambers, no pitting in any of the chambers. the green set has pitting in one combustion chamber, but i don't think its significant. I have soaked the green set in Citric Acid, that cleaned them up a lot, they look pretty nice i think. I also have 2: 4-bolt intakes that i understand make good candidates for 2GC carbs. The orange set $250 The green set $200 The intakes $50/each
