I'm trying to install a new Butler Performance Valley Pan. I test fit it tonight with out the gasket, and when I tighten it, it curls up on the passenger side front and rear (The passenger side middle stays in contact). The Driver's side fits well, and the front and rear pull down, but prior to being withing 1/8 - 1/4 in. of block, the passenger side curls. Will the gasket take up this slack? Seems excessive. Should I glue the gasket to the valley pan and then test fit it? Didn't want to do that until I was sure it fit properly, incase I needed to tweek the pan.
