I have a 1966 GT coupe with a 289 and 4 speed top loader. I'm looking for suggestions for which long tube header to use. I don't want to do any header dimpleing or bashing of the shock tower. I'm also am open to Try Y headers but still concerned about fitment.

thanks Darryl

Not if you get the ones specific for the 64-66. Had another 302 header set and to ding them to get them to fit was an understatement lol
