I am interested in doing ls/vtec, but alot of the heads i have found do not have a dist. with it and was wodering what my options were on which one i could use. I have a 93 hatch and am still using all obd-1 connections. I am not sure which head I am going to use but it will prob. be a b16a1 (cheaper). Which obd-? should I use with this head? Does it matter? Can I use my ls one or a sohc vtec one? Thanks
