I want to run Fenton Headders on my 235 I6 Chevy, the problem I see is the factory manifolds are bolted togther and in the center, there is a exhaust gas heat riser, the fentons or any other headder made for the 235's do not have this provision. Fenton makes a block off plate but I will run this engine on cold mornings of September ( last month of cruising, 1 last show for the year than it's it ) and need the atomization help. I'v seen where there are small tubes run up to the intake but there are no how to's on the net. any idea's? thanks

Matt167,

Now you are talking my engine!
Get yourself an Offenhouser(sp) intake. It can be had with either two or three single throated carbs. But there is a provision for hot water to run inside the manifold to do what you are asking for. I never hooked the water to the manifold because I wanted the gas/air mixture to be as dense as possible. I ran this set-up in a 55 Chevy way back in the day.
