The standard clearance hole size for a 3/8 inch bolt is much smaller than 7/16 inch.
Do you expect that much misalignment?
ya my machine guy told me the same thing. I think its best to open it up so i dont have to do so much die grinding. My cover and axle dont even come close to matching. Maybe the bit didnt chase down the centers exactly when i redrilled and taped for the 3/8"? Anyways it fits about as well as stock exhaust manifolds%)
just another reason why im not keen on using a allen head bolt. They have little shoulder, where as the bolts linked to above have a nice shoulder washer built in to cover these larger holes and take some force.
