max diameter pushrods?.37?

Had a set of custom length push rods made. looks like standard SBC push rods (not even all the sametype!) with Buick ends? These are the correct length as I ordered yet they are .371 compared to the factory buick push rods diameter of .310? Also the oiling holes are a tiny bit larger. Will this cause any issues?

pushrods

I put .371" pushrods in my iron headed car and it was a tight fit. Too tight for a few. Had some light scuffing on two. Had to go to the next size down which was 11/32" rods. These look tight, but there is clearance. I got mine from Manton here in California and I asked for the standard 5/16" rods and the guy there talked me into bigger ones because they are a lot stronger as the dia. goes up. If my heads were off, I would have used the bigger ones and just clearanced the heads a bit. Just needed a little bit off the hole closest to the intake manifold on my car.
