My 351-C needs to be redone and I want to step up to CHI aluminum heads. I'm told that the 3V-185cc heads will make more power along with better throttle response than their 4V heads.
My concern with the 3V heads is the non-stock exhaust port location and want to avoid exhaust system fitment issues. I was hoping to be able to use off the shelf GTS type headers bolted to GTS exhaust/ mufflers.
Are any of you guys that are running the 3V heads using this exhaust system? Any experience with this system or other recommendations would be greatly appreciated.

I used the CHI 2V aluminum heads and a TFC 2V manifold, which looks exactly like the Parker Funnelweb and is also made in Australia. I had no fitment problems with my Big Tube exhuast headers. I can't say what the power output is on the 2V head vs the 3V, but the power is much better from idle on up to 6500 rpm than my old cast iron 4V close chamber heads. I even increased my gas mileage by almost three miles to the gallon and never changed a thing on the carb.
