Call Holley they have a very good hot line and will be glad to help you.

 

It should be a holley 4160 600 cfm 4V, from what Ive googled.

Take a look at this chart.
http://www.holley.com/data/TechServi...%20Listing.pdf
yours is the last listing on page 15. It will tell you what size power valves to get, as well as which rebuild kit to buy.

This manual will tell you how holley's work, and how to tune them:

You'll need a vacuum gauge which you can buy a sears or napa/pepboys/autozone/orielly for about 20 bucks.

 

trail and error if you have a bigger cam then a different power valve is need or you might need a different sec spring to get rid of a bog...remember a holley in stock form is just a start..thier great carbs because there is alot you can tune on them to tailor them to your car
