Hello, well the tall deck 427 is in and bolted in the truck , in the small block engine location , I did not move the mounts forward due to my truck still having the sm420 4 speed , had to do the 2 hammer trick on the fire wall to get the valve covers to to clear at the back of the heads , don't fear I did not do a bash job , you can't even tell I did it , I took my time ! moving the trans forward would have been a mess , and another 500 in cash no doubt 2 drive lines , I have a shaft driven pto on this truck , so I refused that idea right off , now for my issue , I had a set of factory 454 ambulance headers , I thought they would fit , nope , hit the drivers side engine mount , never even tried the passenger side , do doubt the same thing , I took my hot wrench , and a hammer and moved the tube in on the drivers side about a 1/4 inch hopefully wishing that would make it fit , no luck , and going any further will cut flow to much for a tow truck , so has anyone found anything that will fit ? everyone says that the 68-87 or whatever big block truck headers will fit it , with a dig to one tube , and some engine mount reliefing , because it is a tall deck , that seems ok with me if that is the case , I just hate to buy a 200+ set of headers that will not fit , and after you try and stuff them in , as you know they are your , I don't need wall art , I need exhaust lol , I am not above manifolds if they fit , someone please give me any real world info on this that you know is fact , if I need to buy a weld up kit , I can do that too ...

Re: tall deck 427 63 c30 issues HELP !!
I think with where you have the engine mounted, and the fact that you are running a manual trans, you would be best to find a set of big block shorty headers. No, I have not used them. When I installed the big block in my Suburban, I moved the engine forward, made my own motor moung brackets, and used the '73-'87 headers. Of course this is with a TH400. I can't say for sure if they will work with the mechanical clutch linkage, but that is about the only choice you have as far as I know. Also, no matter which headers you choose, with a big block you will have to trim the top flange of the frame alongside the engine. I usually use a '73-'87 frame as a reference as to where and how much to trim.
I do plan on a 454 for my '66 C30 eventually, but I will be moving the engine forward and converting to a hydraulic clutch.
