Retune my entire carb after installing new heads?

Have you actually looked at the baseplate on a Holley?

Never. Nor do I know what size they should actually be to work correctly............Have you measured any?

The secondary t-slots aren't making much of a contribution since they are not exposed at all until about half-throttle where the progressive linkage starts to open the secondary butterflies! They're just barely cracked at idle.

NO ****.....Maybe that's part of your problem.......

Still a rude schmuck, I see. Go back to your "Fantasy Pro Stock" theories and leave this thread alone.

You mean that Prostock engine that ran quicker after they fixed the idle/trasnfer circuit.........Nah that would never be applicable to a stock or modified engine would it. They must have spent billions to get that right.......
