New here and hate to reask for info but i couldn't find what i was looking for.
I am looking for info on head design/config for SR20's. The only thing that i have been able to find is that the 14 and 15 engine's had variable timing. If this is the only change then cool, but the rumors are that the 15 head is better(you don't need lash killers, rocker stoppers) i believe that the 14 and 15 head is the same with a slightly better cam in the 15. This is just for my own knowledge so i can call bullshit when someone is spu-ing at the mouth.

Known facts are
15's crank is lighter, different rings were used and it had a BB turbo.

Any info will be greatly appreciated Thanks in advance
