easy answer vtec head is better especially with turbo. and these guys are fucking retarded when you build ls/vtec b16 heads are better they flow better. thats what i used on my ls/vtec build and i used a golden ls/vtec kit and arp headstuds. the golden eagle kit comes with a headgasket but i would not recomend using it. i used a greddy one and it was nice.
