hi guys , just a quick question ? would standard length risers on stainless marine manifolds work with cam of .224/[email protected]" ? i'm getting away with it now with merc center risers/standard risers. yes this is a small block. wondering if increased flow of manifold might be an issue. thanks

Whats the engine? I put SM standard risers on my mx 6.2 cause I wanted to keep the Q&Q and was told my set up was right on the edge, I've run them for 40+ hrs. with no problems, if your indoubt call Brownie @ SM. Goodluck Steve

well built small block 350. nothing outrageous just carburated.

Just a hunch, I'd go with the longer risers with you dura. @ .050 to be safe, but Brownie would know for sure.
