ok, bought a rebuild very nice stock intake/exhaust manifold off ebay, been cleaned, blasted and painted and is in perfect mint shape, anyways, it bolts up to my 235 perfect but i noticed a few differences in the stock 235 manifold to this one, can I use a stock 235 rochester carb on this no problem? I noticed the vaccum port is also different and larger, but i wont be using it, please let me know if anyone has been in this boat or what works, thanks a million!!!!!
