lightning headers
 
lookin at a set of lightnings. I have the gils on hp500 with silent choice. Lightnings are the standard header and removing silent choice. I dont believe reversion will be a issue with this set up.
However i plan on putting on a set of afr 305 heads and i have a custom ground cam by rmbuilder that i got of a oso'er that had same set up. cam is in225/ex231 582/597 lift on 112.
(numbers are off top of my head, may not be exact but are close). Would reversion be an issue? would the reduced water header be a better choice

I have Lightning headers on my 522, my cam is 242/252 @ .050" and .623/.611 with a 112 LSA and no problems. The Lightning's are taller than stock which helps keep water out of the cylinders.

You will be fine! I have Eickert headers and am running an RM Builder cam that is 234/241 dur .63/.615 lift with 112 lobe sep. I also ran this cam with standard length Stainless Marine Manifolds.

lightning makes a header for silent choice if you want to keep it...
