I have a 68 that was originally a bbc car, but I bought it as a roller. I have a good 427 and several sets of bbc headers - most without part numbers. Looking at photos online of early vette bbc headers, the hedmans i have look like they should fit with some massaging. Can anyone tell me if these look like headers you have used in a bbc 68-73 vette?
Also...I bought a new set of engine mounts and they will not fit onto the stock stands - they lack 1/8"-1/4" inch of width to fit. I picked up another pair today and same issue. The car side motor mount stands are factory,, and have not been built up or welded on. Are the early 68 mounts different? Or am I just getting poor quality mounts at my local parts store?

must be poor mounts. I was using the Energy Dynamics poly mounts and tore them all to hell. I use the Mr Gasket solid mounts and a poly tranny mount with no issues or vibrations
I have been using Hedman headers on my early 1968 for decades without any issues. I never had to massage them to get them to fit. In fact they just bolted right on and never had any issues. Just get the right set and you won't have any problems.
15 years ago I had the same problem with motor mounts. The parts catalogs listed the wrong mounts for a big block corvette. The mount they listed was actually for a BB chevelle.
Read up on this on previous posts...68-early 70 used different width stands (by 1/4"), in 1970 the bbc mounts were changed. Most parts houses sell the 70+ mounts as for 68+. Solution is to buy mounts for a 62-67 BBC vette...unless you want the safety mounts like those that came out in 1970, then the corvette suppliers sell the earlier width mounts with the safety bar built into them in case a mount fails (the engine doesnt torque up thru your glass hood...
