I'd like to replace my 83 exhaust headers and I'd like to keep my dual snorkel air cleaner. My car is dual straight piped-no cats. Can I bolt on the 85 steel headers with the welded on heat riser connection? I know I'd be looking for the 4-1 as the 4-3 were for the vert. The original risers have long since rusted away and finding the replacement for a 1 year mod has been impossible and it doesn't seem to make any sense to do all that work for a cast iron exhaust.

I'm running an Edelbrock 1406 carb, the air pump was replaced with a bracket and the hoses to the air valve were removed. The EGR and pipe/hose to the back of the heads was removed and the holes plugged. Do I need the heat risers for better cold weather performance anymore?

I'd appreciate your comments and/or suggestions. THANKS!
