i'm in the middele of installing my lt1 into my 87 z28 and the driversside exaust manifold doesn't fit. i need to get headers. what do you suggest for those that have already done the installation. thanks. also i need to keep a.i.r. as well

 

bump. i'm not sure which to get. i have the complete exhaust from the lt1 that includes the factory y pipe with all 3 sensors and both converters. what would be the best way to go as far as money is concerned. or how about a caprice manifold. thanks for your help
