I'm running out of time to convert my '61 Belvedere to a Super 6 set up. I'm leaving for Chryslers in Carlisle in 2 weeks. Is it necessary to resurface the manifolds. Will the carb take a kit??? Help out an old man fulfill his dream of meeting all of the Forward Look guys before I go to the Big Penta in the sky.

If the faces of the manifolds clean up well I wouldn't worry about refacing them.

The carb will probably need a kit, and if it is a BBD might have the throttle shaft bores worn out.

Put the stack together and run a good straight edge across the common mating surface of both manifolds and use a feeler gauge set to see what the discrepancy is.... if under .003-4 you should be able to use a felpro composite gasket, if over that (but under .050...lol), or are looking to load the odds of success anyway, get a remflex gasket....

I have 2 different intake/exhaust manifolds. 1 is a WHOLE lot lighter than the others that I have. Which one should I use. The carb is a Carter.

With your time being short, I'd tend to want to put on the heavier iron intake since the AL ones have occasional issues. Just check the flanges for straightness first; if the AL intake set is flatter, I'd use it.

Look up the article in the 'Articles' section of this site for manifold installation if you have not done so already. If your exhaust manifold is warped, bolt the 2 together and take them to a shop with a large belt sander or blanchard grinder for evening out the ports. (I have had some success in a pinch with a 3" belt sander and coarse belts, but you have to remove material slowly and check and re-check constantly for flatness but most folks may not like to do this.)

Some light beads of red high-temp RTV around the exhaust ports on the both sides of gaskets may help seal a small gap. I also like to use a very thin, skim coat of blue RTV around the intake ports; just skim coat, not gobs.

Look at your exhaust riser flapper and make sure it is freed up. If not, you probably can get by with it being stuck closed for a summer time drive. Just make sure it is not stuck open for now.
