idosubaru Posted August 3, 2009 Share Posted August 3, 2009 the difference is in the heads, they have siamesed exhaust ports. you can look up power differences on cars101.com with the 1995 being dual ports and 96 being single port. i would compare those two since they are the most identical except for the exhaust deal. pretty sure the power difference is rather small.

Gloyale Posted August 3, 2009 Share Posted August 3, 2009 The Single port heads (later) have roller rockers and slightly more lift. I've always thought the best combo would be to use the Dual port heads with the rockers and Cam from the later single port head. Link to comment Share on other sites More sharing options...
avk Posted August 3, 2009 Share Posted August 3, 2009 There are roller rockers on 1995 engines as well. Link to comment Share on other sites More sharing options...
