So are most of the guys running b16 heads or something different? The reason I ask is it seems I've seen somewhere that the b18 head flows better in stock form. Also, you said valves and springs. Did you mean retainers or are people running aftermarket valves with 5 angle valve jobs( just an example)? Just trying to make a detailed comparison. Thanks[/QUOTE]Originally Posted by silviadriftr
Yea most of us have Gsr heads,i meant springs and retainers,last year i ran a completley stock head, i had no springs or retainers added,it was completley stock! I will find you the link where they compare them so you can read up on the diffrent heads and how they flow,but a b16 flows almost the same!
