I have a b18a1 out of a 91 integra. I just recieved a b20 nonvtec head from a friend. I also have a b18b head out of a 94 integra.
heads:
1. stock obd0 ls head
2. disassembled obd1 ls head
3. complete* B20 head minus distributor and intake manifold

does anyone have the specs on the differences between these three heads?

I am starting to plan out my next project, which is an obd1 conversion to my car, i have the obd1 ecu, 4 wire o2, obd1 distributor, i am leaving the injectors the way they are so I can take advantage of the mitsubishi 390 injectors eventually. While I am doing the obd1 conversion I plan on swapping out the obd1 ls cams. I also have an obd1 ls manifold and a gsr manifold that came with the b20 head. I was thinking that i could use this to my advantage.

Does either head has any better flow design characteristis? I am aware of the fact that the obd1 ls motors had "better" cams than the obd0 motors. What is the difference between the obd1 ls cams and the cams in the b20 head?

In conclusion my specific question is...

Is my best bet to port the b20 exhaust ports to match up with the stock gsr mainfold that was provided with the head. Then put the obd1 ls intake manifold and distributor on the b20 head,and then slap that on the b18a1 lower end?

kinda confusing but thank you in advance

p.s. I would really like to keep the obd0 head untouched. I figure that the less I have to modify the better. In porting the b20 head to fit the gsr manifold i am setting myself up for later this summer when i can afford to purchase a jdm dc sports header with the 2.5 inch collector. But considering that i can't afford that right now i will make due with what i have available. I also want to use the gsr header because of the placement of the o2 sensor (right now it is in the front of the car) and because the 2 1/4in collector...i have a rs*r exmag gt2 60 mm exhaust... so the more that I can open up the exhaust the better...
