Questions for the Viper Gurus.............................

[99RT10]

Trying to find out when the Gen I heads changed from an round exhaust port design to a D port design? Did it help in better performance? I was thinking it was 1994 at the same time they changed the intake from a 4 rib magnesium to a 3 rib aluminum design. Any know for sure?

Maybe this is one of those "ask SRT" questions. Do we have a section like that somewhere?

Ok found out that ALL exhaust ports are D-ports. Just the manifolds were round. Got that info from the famous Greg Good.......................:D

Manifolds and gaskets went to D port with the 1996 GTS.
