I want to sell my vtec heads but i have a b20z shortblock laying around. I was wondering what people would do. A b16 head obviously flows better but the gsr will bump compression up a little more. Thinking maybe b16a cams in gsr head with b20z bottom end. But I dont know if I want to put the ls vtec b20 in over my current b18c1 in my CRX. Or one wicked Idea would be using the b18c1 bottom end and rods with some 2.0L pistons and using one of the two heads. A high revving b20 would be nice but no oil squirters.
