I want to put headers on my slant, but there does need to be at least some kind of intake heat, or there's going to be trouble

I don't need a choke well...

So, would it work OK to divert some flow from the water pump and run it through the cavity on the bottom of the intake? Seems like a thick aluminum plate with a good gasket seal and a couple of strategically located holes for water inflow and outflow with hose barbs on them ought to work...

What do you think?

See earlier threads (like this one) about intake heat.

I have one on my car and it works extremely well.
