ive been looking for a dohc vtec head to finish my ls vtec..some guy around where i live told me that he will sell me his complete b16b head with type r cams and valvetrain for 300..he says its been laying around for a while and he doesnt mind getting rid of it.. so my question is how can i tell the difference between type r cams, valve train,and a b16b head from all the other heads and componets.. are there any marks , letters , or numbers on the head and parts.. i searched and it said that type r cams have to grooves on the distributor side of them.. and i know that type r valve trains have dual valve springs and all the other heads dont.. so if any one can tell me what i should look for when i look at the head ( prob tomm or the day after).. pictures would be great .. thanks in advance for your help.
