Dart 325 heads would be a normal selection for a 540. With Lemon's headers and a 3.5 inch exhaust, Im thinking your 540 is something more, maybe Dart 345s. A run of the mill 540 is 650hp. A trick 540 is 850hp or so.
There aren't many BBC fans here. Remember you'll make more hp with a plug wire off, than most with a perfect tune, lol.
