ISO BBC performance exhaust
 
On the hunt for either stainless marine, gil, CMI, or any other decent performance manifold with risers out there for a big block chevy. 454 gen 5, bravo 1, 9.6:1 compression, 088 GM iron heads (365 horse heads) Erson marine grind cam with .585" lift on intake and exhaust. Intake duration is 226 @ .050" and exhaust is 218 @.050". Factory GM high rise with a 750 Holley. Was going to go with lightning headers but unfortunately with how my exhaust tips are mounted so they clear my swim deck, they won't fit.

I have a nice clean set of Gill's off my HP500 I'll sell if you're interested. Can take you some pics later today if you wish.

Will they fit a Gen 5 454 head? I can't remember if the HP's exhaust ports are different
