I am rebuilding a Holley 2110 for the center carb on a 3x2 set. I have a kit from Speedway that includes a new power valve. The power valve is unmarked, no idea what power valve it is. The original power valve I removed from the carb is marked 24. I am running two secondary carbs, power valves blocked, no idle circuits, choke, etc. The jets in the center carb are 52's. Should I take a chance on the power valve in the rebuild kit or try to determine a better size? Aluminum heads, Mummert 270 cam, Sanderson headers, Fordomatic.

Thanks.
