I bought a pair of these to use on my 440-1 heads. The bolt holes are not lining up.

Has anyone run into this problem? I was thinking of drilling the holes a bit larger.

I would send them back one time, call Summit and ask them to have them picked up( Call tag) the same time they deliver the new ones BTW, I have seen more than one pair of the die cast Mopar brand BB aluminum valve covers, plain, wrinkle black and polished have issues with the bolt hole locations
