Sanderson Shorty headers are not log style manifolds. Sanderson headers are headers...they have individual exhaust piping for each port. Totally different than stock manifolds.

 

Curious for all those with headers... did you fill in the exh. crossovers and/or weld metal to bridge those center exh. port gaps (insert proper terminology) on the heads?

 

With the Blue paint I was thinking maybe you had a 455 and that they made them in years past and I would start to look for them on the net.
Thanks

 

455 Sanderson headers? I don't see that on there site. Link?

Be nice to see a dyno test with all the choices of exhaust. (Dreamer)
I know it would vary from engine HP levels. Still would be interesting to see.
I have read where headers added 25+ HP over W/Z.

Center dump only (I think)....

 

Why not replace the motor mounts it is easy to do.

 

BTR Dyno tests, headers vs WZ's..

 

???
I just see W/Z's....
