Ok ive been reading the threads on here, but ive seen some discussions about which is the best head for the D15b non vtec, but a lot of them were older posts. I was hoping to get some more recent opinions if someone has done anything different, or just the best head for my motor. Any suggestions? (other than a complete motor swap - money is tight lol)

 

id say the d16z6.

 

thats what i was looking at, but i was hoping someone could tell me the difference between the d16z6 and the d16y8??? im seeing a lot of both so its making it hard to decide =/

 

Z6 is OBD1, go for that.

Google is your friend for common questions like "difference between z6 and y8".

 

Z6 has better chamber than the y8. Plus if you did a complete y8 the IM is retard looking and doesnt flow as good as the z6 IM. Depending on the pistons you use you can get a really good high conpression ration out of the z6 head 10:1, 11:1 dont go to 12 unless your going all out with computer, map, fuel pump, tuning ect. Unless your lookig to do low comp go with the y8. Just my opinion

 

looks like the z6 win =) thanks guys!
