I question 4 sizes up on the mains...that is a big jump. A stock Holley HP is about 2 sizes too rich on the mains. As I recall, this is a Holley HP from a custom carb shop, so it should be right-on as far as the mains. If this is a custom carb then you should go back to who ever built it. They know how it's calibrated and if they are good they know what needs to be changed to correct it to your engine mods...it might be something that needs to go back to them to recalibrate it.
