I would like to change from stock exhaust manifold with single exhaust pipe to headers with dual exhaust. I currently have a Weber 32/36 carb setup on stock manifold and it is running well. I have an oil filter setup on the stock manifold.

I am planning on running the stock intake manifold with one carb, after market heat plate, then dual exhaust with glass packs late in the exhaust run.
I may upgrade the stock intake manifold to a dual carb setup at a later date.

The corvette 55 intake for the 235 is probably the best, but I probably won't be able to find or afford one.
I've heard conflicting reports regarding fit for Williams headers. I've also read they fit the stock intake as well as the Offenhauser. I kind of like this as it allows me to upgrade to dual carb setup in the future, if I decide to do that. Langdon and National Chevy Association both sell Williams headers.

I have read a lot of threads about header choices but nothing too recent.

Is there any experience lately with the Williams headers? Did anyone with this setup run the oil filter mount?

Thanks,
Joe
