I have used the Imco stainless riser on the stock manifolds but you will not gain much.
For bolt on upgrades: Replace your intake with one of these.

and change the entire exhaust with a good flowing alum manifolds and rises like Stainless Marine.

how long would an aluminum intake last in a raw water cooled application , or is there slip in bronze jacketing that can be used ?
anyone ever used the aluminum manifolds/risers from GLM?
they look cost effective and supposedly have the indevidual runners that help your power production

No bronze insert in that manifold. An aluminum intake will last for a few years untreated. You can have in hardcoat anodized for added protection.
The GLMs are a decent product but you will not gain much power. The least expensive good flowing manifolds are Revolution Marine.
