i had a problem in my 74 satellite with their headers, when i ran a small block. the top two tubes had to be mashed almost flat for the header to fit. i sent the header back and they worked with me and sent me a custom header back. and yes for the money they should drop in like a glove. with a set of $200 hedmans i had to ding them and mash them in no less than 17 spots to get them into the car.
